电泳（SDS-PAGE）
Human MAT2A Protein, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 90% (With Star Ribbon Pre-stained Protein Marker).
活性（Bioactivity）
Measured via hydrolysis of ATP during synthesis of S-adenosylmethionine. The specific activity is >200 pmol/min/μg (QC tested).
Protocol
背景（Background）
The protein encoded by this gene catalyzes the production of S-adenosylmethionine (AdoMet) from methionine and ATP. AdoMet is the key methyl donor in cellular processes. [provided by RefSeq, Jun 2011]
