In enzymology a S-methyl-5′-thioadenosine phosphorylase (EC 2.4.2.28) is an enzyme that catalyzes the chemical reactionS-methyl-5′-thioadenosine + phosphate adenine + S-methyl-5-thio-alpha-D-ribose 1-phosphateThus 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.
