In enzymology, a S-methyl-5'-thioadenosine phosphorylase () is an enzyme that catalyzes the chemical reaction :S-methyl-5'-thioadenosine + phosphate adenine + S-methyl-5-thio-alpha-D-ribose 1-phosphate Thus, the two substrates of this enzyme are S-methyl-5'-thioadenosine and phosphate, whereas its two products are adenine and S-methyl-5-thio-alpha-D-ribose 1-phosphate. This enzyme belongs to the family of glycosyltransferases, specifically the pentosyltransferases. The systematic name of this enzyme class is S-methyl-5-thioadenosine:phosphate S-methyl-5-thio-alpha-D-ribosyl-transferase. Other names in common use include 5'-methylthioadenosine nucleosidase, 5'-deoxy-5'-methylthioadenosine phosphorylase, MTA phosphorylase, MeSAdo phosphorylase, MeSAdo/Ado phosphorylase, methylthioadenosine phosphorylase, methylthioadenosine nucleoside phosphorylase, 5'-methylthioadenosine:phosphate methylthio-D-ribosyl-transferase, and S-methyl-5-thioadenosine phosphorylase. This enzyme participates in methionine metabolism. ==Structural studies== As of late 2007, 20 structures have been solved for this class of enzymes, with PDB accession codes , , , , , , , , , , , , , , , , , , , and . 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「S-methyl-5'-thioadenosine phosphorylase」の詳細全文を読む スポンサード リンク
