In enzymology, a S-methyl-5-thioribose kinase () is an enzyme that catalyzes the chemical reaction :ATP + S-methyl-5-thio-D-ribose ADP + S-methyl-5-thio-alpha-D-ribose 1-phosphate Thus, the two substrates of this enzyme are ATP and S-methyl-5-thio-D-ribose, whereas its two products are ADP and S-methyl-5-thio-alpha-D-ribose 1-phosphate. This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:S-methylmethyl-5-thio-D-ribose 1-phosphotransferase. Other names in common use include 5-methylthioribose kinase (phosphorylating), methylthioribose kinase, 5-methylthioribose kinase, and ATP:S5-methyl-5-thio-D-ribose 1-phosphotransferase. This enzyme participates in methionine metabolism. ==Structural studies== As of late 2007, 6 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-thioribose kinase」の詳細全文を読む スポンサード リンク
