Glycan arrays consisting of 367 diverse glycans with and without the presence of one of three spacers (sp2, sp3 or sp4 [49 (link)]) were prepared from two previously described glycan libraries [83 (link),84 (link)]. Amine containing glycans with spacer’s sp2, sp3 or sp4 were synthesised as previously described [49 (link)] and glycans without spacers were amine functionalised as previously published [85 (link)]. All glycans were suspended in 1:1 DMF:DMSO at a concentration of 500 mM and were printed onto SuperEpoxy 2 glass slides (ArrayIt, Sunnyvale, CA) using a ArrayIt SpotBot Extreme array spotter in a six pin subarray print per glass slide format. All glycans were printed in replicates of four, including four FITC control spots as well as additional position controls (S1 Fig), per subarray using SMP4 pins and a contact time of 1 second at 60% relative humidity, with pins being reloaded after every 12 spots.
Prior to performing glycan array experiments, slides were scanned using a ProScanArray Microarray 4-laser scanner (Perkin Elmer, Waltham, MA) using the blue argon 488 laser set to the FITC settings (492 nm excitation and 517 nm emission). Array slides were blocked with 0.1% BSA in 50 mM phosphate buffered saline (PBS), pH 7.4 for 5 min at 22°C. After washing with PBS, each slide was dried by placing them in an empty 50 mL tube and centrifuging for 5 min at 200 x g (900 rpm). Recombinant TconTS-LD (2 μg) was incubated at a molar ratio of 1:2:3 with anti His-tag mouse polyclonal antibody (10 mg/mL, Cell Signalling Technology), anti mouse-IgG-Alexa555 conjugated rabbit polyclonal antibody (2 mg/mL, Life Technologies) and anti rabbit-IgG-Alexa555 conjugated goat polyclonal antibody (2 mg/mL, Life Technologies) in 50 mM PBS, pH 7.4 containing 0.1% BSA and 10 mM maltotriose for 15 min on ice protected from light. All subarrays on the slide were isolated using a Gene Frame (1.5 x 1.6 cm, 65 μL, Abgene, Epsom, UK) prior to the addition of the TconTS-LD-antibody mix to the array. A coverslip was applied to the GeneFrame and array slides incubated for 30 min at 22°C in the dark. The GeneFrame and coverslip were subsequently removed and the slide gently washed twice with 50 mM PBS, pH 7.4 containing 0.01% TWEEN 20 and 10 mM maltose, and once with 50 mM PBS, pH 7.4 containing 10 mM maltose. Slides were dried by centrifugation for 5 min at 200 x g (900 rpm), allowed to air dried for a further 5 min, and the fluorescence associated with the array spots detected using the microarray scanner settings outlined above. Image analysis and spot visualisation was performed using the ProScanArray software, ScanArray Express (Perkin Elmer). The resulting images were visually examined. Fluorescence signals were judged as being positive, if all four replicates for a glycan were clearly detectable (S1 Fig).

HeLa cells transfected with control or GRASP RNAi were washed with cold PBS, scraped and collected by centrifugation. Proteins were harvested from the cell pellets as previously described53 (link). Briefly, the cell pellets were resuspended in ice-cold water and disrupted by Dounce homogenization on ice. The homogenate was adjusted to 4:8:3::choloroform:methanol:water before removal from ice. After 18 hours of end-over-end agitation (Nutator), the insoluble proteinacious material was collected by centrifugation. Following re-extraction of the pellet three times with 4:8:3 and once with ice-cold 80% acetone (v/v, aqueous) the final pellet was dried under a gentle stream of nitrogen and stored as a fine white powder. All supernatants were combined and dried under nitrogen for analysis of LLO and FOS. Protein content of the powder was determined by BCA assay (Pierce). N-linked glycans were harvested from the protein powder as previously described53 (link). Generally, 2 mg of protein powder (dry weight) was resuspended and digested with trypsin/chymotrypsin. Glycopeptides were enriched by Sep-Pak C18 cartridge chromatography and subjected to digestion with PNGase F for 18 h at 37°C. Released oligosaccharides were separated from residual peptide by Sep-Pak C18 clean-up and permethylated prior to mass spectrometric analysis54 .
For analysis of LLO and FOS, the dried supernatants from the cell extraction were resuspended in 50% aqueous methanol and loaded onto a Sep-Pak C18 column previously washed with methanol and equilibrated in water. FOS were collected in the run-through and a subsequent water wash, which were combined and dried. The collected FOS fraction was permethylated for analysis by MS54 . The LLOs remained bound to the Sep-Pak C18 column and were recovered by elution with methanol and 10:10:3::chloroform:methanol:water as previously described55 (link). Briefly, after drying, the LLO fraction was resuspended in 10:10:3 and applied to a DEAE-cellulose column. Following washes with 10:10:3 to remove neutral lipids, the LLOs were eluted in 10:10:3 containing 300 mM ammonium acetate. The eluted LLOs were recovered by phase partition into the organic layer, which was dried and resuspended in 0.1 M HCl in isopropanol. The LLO oligosaccharides were released from dolichol pyrophosphate by heating at 50°C for 1 h. After cooling and drying under nitrogen, the released LLO oligosaccharides were resuspended in water and recovered in the aqueous phase after addition of n-butanol. The LLO oligosaccharides in the aqueous phase were dried by lyophilization and permethylated for analysis by MS54 .
Permethylated N-linked, FOS, and LLO glycans were analyzed by nanospray ionization mass spectrometry using an ion trap instrument (NSI-LTQ Orbi Discoverer, Thermo-Fisher) by dissolving in 1 mM NaOH in 50% methanol and directly infusing into the instrument at a syringe flow rate of 0.40–0.60 µl/min. For fragmentation by CID in MS/MS and MSn modes 40% collision energy was applied. The total ion mapping (TIM) functionality of the XCalibur software package (version 2.0) was utilized to detect and quantify the prevalence of individual glycans in the total glycan profile. Most permethylated oligosaccharides were identified as singly, doubly, and triply charged species by NSI-MS. TIM peaks for all charge states of a given ion with m/z ≤ 2000 were summed together for quantification. Glycan quantification was performed relative to a known quantity of external standards (maltotriose and maltotetraose, Supelco) that was permethylated with heavy methyliodide (13CH3I) and spiked into the sample matrix.

To verify substrate hydrolysis and detect the products formed, MAL1 WT and mutant Asp199Ala reaction mixtures were separated on TLC plates (Silica Gel 60 F254) with concentrating zones (Merck, Germany). The reactions were conducted in maltase buffer at 37°C, and at certain time points aliquots were withdrawn and heated for 5 min at 96°C to inactivate the enzyme. Concentrations of 1‐kestose, nystose, melezitose and maltotriose in the reaction mixture were 50 mm, 6‐kestose was used at 10 mm, and malt extract and IMOs were used at 2% w/v. Palatinose and maltose were used at 100 mm in the assay of catalytic ability of the Asp199Ala mutant. Maltase was added at 1 U/ml reaction mixture, or at 247 µg/ml in the case of the Asp199Ala mutant. The amount of protein equivalent to 1 U was determined through activity assays on 1 mmα‐pNPG; 0.5 µl of each of the stopped reaction mixtures were spotted onto TLC plates and sugars were separated with two runs in chloroform:acetic acid:water (6:7:1 v/v/v) (Stingele et al., 1999). Sugars were visualized by immersion of the plates in aniline–diphenylamine reagent and subsequent heating of the dried plates at 120°C (Jork et al., 1990).

Authentication of the molecular docking procedure was performed by redocking the two cocrystallized ligands, MCC950 and α-maltotriose, in the active sites of NLRP3 and the ASC-CARD, respectively. The performed validation reproduced the same binding patterns and interactions of the cocrystallized ligands, confirming that the docking setup used was appropriate for the proposed docking study. This was illustrated by the perfect alignment between the self-docked poses and the cocrystallized ligands MCC950 and α-maltotriose, with root mean square deviations (RMSDs) of 1.262 and 0.52 Å and docking scores (S) of -9.2 and -9.9 kcal mol -1 in the binding sites of NLRP3 and ASC-CARD, respectively.

To determine which OD600 readings corresponded to exponential phase, a 48-hour broth culture (mNYC III supplemented with 1% oyster glycogen or maltotriose) was diluted 1:10 and 200 µL aliquots of the diluted sample were pipetted into 8 wells of a flat bottom 96-well plate (VWR Tissue Culture Plate, Non-treated, Sterilized, Non-Pyrogenic, Avantor). The 96-well plate was then incubated over the course of 72 hours at 37°C under anaerobic conditions (GasPak EZ Anaerobe Gas Generating Pouch System with Indicator, BD) with OD600 readings taken periodically over 72 hours with a microplate reader (Varikoskan LUX 3020-1160). The time spent to read the OD600 was minimized to ensure little disturbance and the GasPak was replaced at each time point. Growth curves were performed for each strain in each condition (maltotriose or glycogen). Data was fitted to a logistic growth model using GraphPad Prism version 10.1.0 for macOS (GraphPad Software, Boston, USA).
