Glutamine

Glutamine is a nonessential amino acid that plays a crucial role in various metabolic processes within the human body.
It serves as a precursor for the synthesis of other amino acids, proteins, and nucleic acids, and is also involved in energy production, acid-base balance, and immune function.
Glutamine is particularly important for the health and function of the gastrointestinal tract, muscle tissue, and the brain.
Adequate glutamine levels are essential for maintaining overall wellbeing and supporting the body's natural healing and repair processes.
Researchers continue to explore the potential therapeutic applications of glutamine supplementation in a wide range of clinical conditions, including sports performance, critical illness, and neurological disorders.
This MeSH term provides a concise, informative overview of the physiological importance and research areas related to glutamine.

An Escherichia coli K12 strain was grown in standard LB medium, harvested, washed in PBS, and lysed in BugBuster (Novagen Merck Chemicals, Schwalbach, Germany) according to the manufacturer's protocol. HeLa S3 cells were grown in standard RPMI 1640 medium supplemented with glutamine, antibiotics, and 10% FBS. After being washed with PBS, cells were lysed in cold modified RIPA buffer (50 mm Tris-HCl, pH 7.5, 1 mm EDTA, 150 mm NaCl, 1% N-octylglycoside, 0.1% sodium deoxycholate, complete protease inhibitor mixture (Roche)) and incubated for 15 min on ice. Lysates were cleared by centrifugation, and after precipitation with chloroform/methanol, proteins were resuspended in 6 m urea, 2 m thiourea, 10 mm HEPES, pH 8.0. Prior to in-solution digestion, 60-μg protein samples from HeLa S3 lysates were spiked with either 10 μg or 30 μg of E. coli K12 lysates based on protein amount (Bradford assay). Both batches were reduced with dithiothreitol and alkylated with iodoacetamide. Proteins were digested with LysC (Wako Chemicals, GmbH, Neuss, Germany) for 4 h and then trypsin digested overnight (Promega, GmbH, Mannheim, Germany). Digestion was stopped by the addition of 2% trifluroacetic acid. Peptides were separated by isoelectric focusing into 24 fractions on a 3100 OFFGEL Fractionator (Agilent, GmbH, Böblingen, Germany) as described in Ref. 45 (link). Each fraction was purified with C18 StageTips (46 (link)) and analyzed via liquid chromatography combined with electrospray tandem mass spectrometry on an LTQ Orbitrap (Thermo Fisher) with lock mass calibration (47 (link)). All raw files were searched against the human and E. coli complete proteome sequences obtained from UniProt (version from January 2013) and a set of commonly observed contaminants. MS/MS spectra were filtered to contain at most eight peaks per 100 mass unit intervals. The initial MS mass tolerance was 20 ppm, and MS/MS fragment ions could deviate by up to 0.5 Da (48 (link)). For quantification, intensities can be determined alternatively as the full peak volume or as the intensity maximum over the retention time profile, and the latter method was used here as the default. Intensities of different isotopic peaks in an isotope pattern are always summed up for further analysis. MaxQuant offers a choice of the degree of uniqueness required in order for peptides to be included for quantification: “all peptides,” “only unique peptides,” and “unique plus razor peptides” (42 (link)). Here we chose the latter, because it is a good compromise between the two competing interests of using only peptides that undoubtedly belong to a protein and using as many peptide signals as possible. The distribution of peptide ions over fractions and samples is shown in supplemental Fig. S1.

The final targeting constructs were prepared for ES cell electroporation from 2 ml of culture (2X LB plus antibiotics) in 96-well format using the Qiagen Turboprep kit. Before electroporation, vectors were linearized with AsiSI and examined by gel electrophoresis. For most clones, the digested DNA migrated as a single high-molecular-mass band of the expected size (Supplementary Fig. 5). Occasionally, contaminating smaller molecular mass bands were also observed on the gel (DNA quality failures).
JM8 mouse ES cell lines derived from the C57BL/6N strain were grown either on a feeder layer of SNL6/7 fibroblasts (neomycin and/or puromycin resistant) or on gelatinized tissue culture plates16 (link). Both feeder-independent and feeder-dependent lines were maintained in Knockout DMEM (500 ml, Gibco) supplemented with 2 mM glutamine, 5 ml 100× β-mercaptoethanol (360 μl in 500 ml PBS, filter sterilized), 10–15% fetal calf serum respectively (Invitrogen) and 500 U ml−1 leukaemia-inhibitory factor (ESGRO, Millipore). Trypsin solution was prepared by adding 20 ml of 2.5% trypsin solution (Gibco) and 5 ml chicken serum (Gibco) to 500 ml filter-sterilized PBS containing 0.1 g EDTA (Sigma) and 0.5 g d-glucose (Sigma).
Electroporations of ES cells were carried out in a 25-well cuvette using the ECM 630 96-well electroporator /HT-200 automatic plate handler (BTX Harvard Apparatus; set at 700 V, 400 Ω, 25 μF). Immediately before electroporation, cell suspensions of ~1 × 107 cells and ~2 μg of linearized targeting vector DNA were mixed in a final volume of 120 μl PBS. Cells were seeded onto a 10-cm dish (with feeders or gelatin) and colonies were picked after 10 d of selection in 100 μg (active) per ml Geneticin (Invitrogen). To expand cells into duplicate wells for archiving and preparation of genomic DNA, confluent cultures of JM8 ES cells grown on feeder cells were washed twice with pre-warmed PBS and trypsinized for 15 min at 37 °C. Five volumes of pre-warmed media were added and the cells were gently dispersed by tituration and passed at a dilution of 1:4 into new plates containing feeder cells. Passage of cells grown on gelatinized plates was carried out in a similar manner except that the cells were trypsinized for 10 min and passed at a dilution of 1:6 into freshly gelatin-coated plates (0.1% gelatin, Sigma G1393). Culture medium was replaced daily and cells reached confluence 2 days after passage. To archive ES cell clones, trypsinized cells from confluent 96-well plates were transferred in 200 μl freezing medium (Knockout DMEM, 15% serum/ 10% DMSO) to 96-well cryovials (Matrix) and overlayed with sterile mineral oil. The cells were placed at −80 °C overnight and then transferred to liquid nitrogen.

All of the UM-SCC cell lines were established from head and neck cancer patients who gave written informed consent in studies reviewed and approved by the University of Michigan Medical School Institutional Review Board. Current and early passage human UM-SCC cell lines established at the University of Michigan (1 –3 (link), 5 (link), 30 (link)) were retrieved from liquid nitrogen storage. Cell lines were grown in complete Dulbecco’s Modified Eagle’s Medium (cDMEM) containing 2 mM L-glutamine, 1% nonessential amino acids, 1% Penicillin-Streptomycin (Invitrogen, Carlsbad, CA) and 10% fetal bovine serum, in a humidified atmosphere of 5% CO2 at 37°C. All cell lines were tested for mycoplasma, using the MycoAlert Detection Kit (Cambrex, Rockland, ME). Contaminated cultures were treated with Plasmocin according to the manufacturer’s protocol, and testing was repeated at monthly intervals.

PBMC (1 × 106/mL) are cultured in RPMI 1640 supplemented with 10% human serum, 2 mM L-glutamine, and 1% penicillin (Invitrogen Ltd, Paisley, UK) and incubated at 37°C in a humidified 5% CO2 atmosphere for 2 h in a 12-well plate. After 2 h, non-adhering PBMCs are harvested and discarded; monocytes (adhering cells) are culture in medium alone (unstimulated) or primed with 2 μg/mL LPS for 2 h (Sigma–Aldrich, St. Louis, MO) before stimulation with Nigericine (5 μM) (Sigma–Aldrich) for 1 h at 37°C in a humidified 5% CO2 atmosphere. Adhering cells (monocytes) are then collected by trypsin treatment and prepared for FlowSight analysis by immunofluorescence staining as THP1-derived macrophage (see above).

Fresh or frozen bone marrow cells were used to generate BMDM as previously described [8] (link), using L929-cell conditioned medium (LCCM) as a source of granulocyte/macrophage colony stimulating factor [9] (link). The cells were resuspended in 10 ml bone marrow differentiation media (R20/30), which is RPMI1640 supplemented with 20% fetal bovine serum (Gibco, cat. 12657-029), 30% LCCM, 100 U/ml penicillin, 100 µg/ml streptomycin, and 2 mM L-glutamine. Cells were seeded in non-tissue culture treated Optilux Petri dishes (BD Biosciences) and incubated at 37°C in a 5% CO2 atmosphere. Four days after seeding the cells, an extra 10 ml of fresh R20/30 were added per plate and incubated for an additional 3 days. To obtain the BMDM, the supernatants were discarded and the attached cells were washed with 10 ml of sterile PBS. Ten ml of ice-cold PBS were added to each plate and incubated at 4°C for 10 minutes. The macrophages were detached by gently pipetting the PBS across the dish. The cells were centrifuged at 200× g for 5 minutes and resuspended in 10 ml of BMDM cultivation media (R10/5), which is composed of RPMI 1640, 10% fetal bovine serum, 5% LCCM and 2 mM L-glutamine. The cells were counted, seeded and cultivated in tissue culture plates 12 hours before any further experimental procedure.

Impact of IL-2 signalling on Teff responses is characterised in a T cell activation assay, in which intracellular granzyme B (GrB) upregulation and proliferation are examined. Previously frozen primary human Pan T cells (Stemcell Technologies) are labelled with eFluor450 cell proliferation dye (Invitrogen) according to manufacturer's recommendation, and added to 96-U-bottom well plates at 1×105 cells/well in RPMI 1640 (Life Technologies) containing 10% FBS (Sigma), 2 mM L-Glutamine (Life Technologies) and 10,000 U/ml Pen-Strep (Sigma). The cells are then treated with 10 μg/ml anti-CD25 antibodies or control antibodies followed by Human T-Activator CD3/CD28 (20:1 cell to bead ratio; Gibco) and incubated for 72 hrs in a 37° C., 5% CO2 humidified incubator. To assess T cell activation, cells are stained with the eBioscience Fixable Viability Dye efluor780 (Invitrogen), followed by fluorochrome labelled antibodies for surface T cell markers (CD3-PerCP-Cy5.5 clone UCHT1 Biolegend, CD4-BV510 clone SK3 BD Bioscience, CD8-Alexa Fluor 700 clone RPA-T8 Invitrogen, CD45RA-PE-Cy7 clone HI100 Invitrogen, CD25-BUV737 clone 2A3 BD Bioscience) and then fixed and permeabilized with the eBioscience™ Foxp3/Transcription Factor Staining Buffer Set (Invitrogen) before staining for intracellular GrB and intranuclear FoxP3 (Granzyme B-PE clone GB11 BD Bioscience, FoxP3-APC clone 236A/E7). Samples are acquired on the Fortessa LSR X20 Flow Cytometer (BD Bioscience) and analysed using the BD FACSDIVA software. Doublets are excluded using FCS-H versus FCS-A, and lymphocytes defined using SSC-A versus FCS-A parameters. CD4+ and CD8+ T cell subsets gated from the live CD3+ lymphocytes are assessed using a GrB-PE-A versus proliferation eFluor450-A plot.

A. Seed Treatment with Isolated Microbe

In this example, an isolated microbe from Tables 1-3 will be applied as a seed coating to seeds of corn (Zea mays). Upon applying the isolated microbe as a seed coating, the corn will be planted and cultivated in the standard manner.

A control plot of corn seeds, which did not have the isolated microbe applied as a seed coating, will also be planted.

It is expected that the corn plants grown from the seeds treated with the seed coating will exhibit a quantifiably higher biomass than the control corn plants.

The biomass from the treated plants may be about 1-10% higher, 10-20% higher, 20-30% higher, 30-40% higher, 40-50% higher, 50-60% higher, 60-70% higher, 70-80% higher, 80-90% higher, or more.

The biomass from the treated plants may equate to about a 1 bushel per acre increase over the controls, or a 2 bushel per acre increase, or a 3 bushel per acre increase, or a 4 bushel per acre increase, or a 5 bushel per acre increase, or more.

In some aspects, the biomass increase is statistically significant. In other aspects, the biomass increase is not statistically significant, but is still quantifiable.

B. Seed Treatment with Microbial Consortia

In this example, a microbial consortium, comprising at least two microbes from Tables 1-3 will be applied as a seed coating to seeds of corn (Zea mays). Upon applying the microbial consortium as a seed coating, the corn will be planted and cultivated in the standard manner.

C. Treatment with Agricultural Composition Comprising Isolated Microbe

In this example, an isolated microbe from Tables 1-3 will be applied as an agricultural composition, administered to the corn seed at the time of sowing.

For example, it is anticipated that a farmer will apply the agricultural composition to the corn seeds simultaneously upon planting the seeds into the field. This can be accomplished, for example, by applying the agricultural composition to a hopper/bulk tank on a standard 16 row planter, which contains the corn seeds and which is configured to plant the same into rows. Alternatively, the agricultural composition can be contained in a separate bulk tank on the planter and sprayed into the rows upon planting the corn seed.

A control plot of corn seeds, which are not administered the agricultural composition, will also be planted.

The inoculants were prepared from isolates grown as spread plates on R2A incubated at 25° C. for 48 to 72 hours. Colonies were harvested by blending with sterile distilled water (SDW) which was then transferred into sterile containers. Serial dilutions of the harvested cells were plated and incubated at 25° C. for 24 hours to estimate the number of colony forming units (CFU) in each suspension. Dilutions were prepared using individual isolates or blends of isolates (consortia) to deliver 1×105 cfu/microbe/seed and seeds inoculated by either imbibition in the liquid suspension or by overtreatment with 5% vegetable gum and oil.

Seeds corresponding to the plants of table 15 were planted within 24 to 48 hours of treatment in agricultural soil, potting media or inert growing media. Plants were grown in small pots (28 mL to 200 mL) in either a controlled environment or in a greenhouse. Chamber photoperiod was set to 16 hours for all experiments on all species. Air temperature was typically maintained between 22-24° C.

Unless otherwise stated, all plants were watered with tap water 2 to 3 times weekly. Growth conditions were varied according to the trait of interest and included manipulation of applied fertilizer, watering regime and salt stress as follows:

    • Low N—seeds planted in soil potting media or inert growing media with no applied N fertilizer
    • Moderate N—seeds planted in soil or growing media supplemented with commercial N fertilizer to equivalent of 135 kg/ha applied N
    • Insol P—seeds planted in potting media or inert growth substrate and watered with quarter strength Pikovskaya's liquid medium containing tri-calcium phosphate as the only form phosphate fertilizer.
    • Cold Stress—seeds planted in soil, potting media or inert growing media and incubated at 10° C. for one week before being transferred to the plant growth room.
    • Salt stress—seeds planted in soil, potting media or inert growing media and watered with a solution containing between 100 to 200 mg/L NaCl.

Untreated (no applied microbe) controls were prepared for each experiment. Plants were randomized on trays throughout the growth environment. Between 10 and 30 replicate plants were prepared for each treatment in each experiment. Phenotypes were measured during early vegetative growth, typically before the V3 developmental stage and between 3 and 6 weeks after sowing. Foliage was cut and weighed. Roots were washed, blotted dry and weighed. Results indicate performance of treatments against the untreated control.

The data presented in table 15 describes the efficacy with which a microbial species or strain can change a phenotype of interest relative to a control run in the same experiment. Phenotypes measured were shoot fresh weight and root fresh weight for plants growing either in the absence of presence of a stress (assay). For each microbe species, an overall efficacy score indicates the percentage of times a strain of that species increased a both shoot and root fresh weight in independent evaluations. For each species, the specifics of each independent assay is given, providing a strain ID (strain) and the crop species the assay was performed on (crop). For each independent assay the percentage increase in shoot and root fresh weight over the controls is given.

Directed TpH Engineering

It was found that Homo sapiens TpH2, i.e., the fragment set forth as SEQ ID NO:13; hsTpH2, was sensitive to p-chlorophenylalanine. However, mutations at residues N97 and/or P99 were found to confer resistance to p-chlorophenylalanine and to exhibit improved 5HTP biosynthesis after growing cells in the presence of 100 mg/l of tryptophan overnight at 3TC. A further, saturated mutagenesis, study found that isoleucine (I) was a beneficial amino acid change at residue N97, while cysteine (C), aspartic acid (D), leucine (L) and glutamine (Q) were shown to be beneficial at residue P99. In particular, the combined changes 1\197I/P99D in hsTpH2 showed a >15% increase in 5HTP production in the presence of 100 mg/l tryptophan and the combined changes N97I/P99C in hsTpH2 showed a >25% increase in 5HTP biosynthesis, over the parent TPH2 sequence (SEQ ID NO:13) after acquiring the E2K mutation.

Example 2

Prokaryotic GS-I proteins found in some eukaryotes frequently display no GS catalytic activity and may have different functions. In humans, for example, most tissues/organs express only catalytically-active GS-II. In contrast, human GS-I does not exhibit GS activity. It is expressed only in the lens of the eye and has designated lengsin (lens GS-like protein), probably with a structural role.

To examine the catalytic activity of PfGS-I, PfGS-I gene was cloned and expressed in E. coli and then GS activity of the purified protein was assayed. PfGS-I produced glutamine from glutamate in the presence of ATP, Mg2+ and ammonia (FIG. 2A) demonstrates that PfGS-I is a functional GS.
