Protein Information (annotations from UniProt)

Database IDHIV0001716
UniProt IDQ9NZL9
Primary gene name(s)MAT2B
Synonym gene name(s)TGR
Protein nameMethionine adenosyltransferase 2 subunit beta
Protein functionRegulatory subunit of S-adenosylmethionine synthetase 2, an enzyme that catalyzes the formation of S-adenosylmethionine from methionine and ATP. Regulates MAT2A catalytic activity by changing its kinetic properties, increasing its affinity for L-methionine, PubMed:10644686, PubMed:23189196, PubMed:25075345. Can bind NADP, in vitro, PubMed:23189196, PubMed:23425511. {ECO:0000269|PubMed:10644686, ECO:0000269|PubMed:23189196, ECO:0000269|PubMed:23425511, ECO:0000269|PubMed:25075345}.
