In enzymology a phosphomethylpyrimidine kinase (EC 2.7.4.7) is an enzyme that catalyzes the chemical reactionATP + (4-amino-2-methylpyrimidin-5-yl)methyl phosphate ADP + (4-amino-2-methylpyrimidin-5-yl)methyl diphosphateThus the two substrates of this enzyme are ATP and (4-amino-2-methylpyrimidin-5-yl)methyl phosphate whereas its two products are ADP and (4-amino-2-methylpyrimidin-5-yl)methyl diphosphate.This enzyme belongs to the family of transferases to be specific those transferring phosphorus-containing groups (phosphotransferases) with a phosphate group as acceptor.
