Kinetic Analysis of MAT2A ATPase Activity

Check if the same lab product or an alternative is used in the 5 most similar protocols
ATP hydrolysis by MAT2A was analyzed in reactions with 50 mM Tris-HCl pH 8.0, 50 mM KCl, 10 mM MgCl2, and 200 μM ATP. Control reactions contained 10 μM ammonium vanadate (Sigma) and those with AdoMet contained 80 μM AdoMet (Sigma). Reactions were performed from 25 °C on a heat-block and were started with the addition of 5 μM MAT2A and timepoints were taken from 0-4 hrs and quenched in 0.01 M sulfuric acid and placed on ice. Samples were briefly centrifuged to pellet the precipitated protein. Samples were analyzed on a Waters HPLC using Waters C18 column 300 mm x 3.9 mm. The buffer system was buffer A: 12.5 mM KH2PO4 pH 6 + 2 mM tetrabutylammonium bisulfate and buffer B: 50% buffer A + 50 % acetonitrile. Samples were injected to a gradient program with 100% buffer A to 100% B. The amount of ADP formed for each timepoint was calculated based on the area under the curve of the ADP and ATP peaks. The concentration of ADP in each sample was determined by the ratio of the ADP peak compared to the total amount of ATP and ADP in the sample.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
