In enzymology a S-methyl-5-thioribose kinase (EC 2.7.1.100) is an enzyme that catalyzes the chemical reactionATP + S-methyl-5-thio-D-ribose ADP + S-methyl-5-thio-alpha-D-ribose 1-phosphateThus 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.
