Phosphomethylpyrimidine kinase


Phosphomethylpyrimidine kinase

In enzymology, a phosphomethylpyrimidine kinase (EC number|2.7.4.7) is an enzyme that catalyzes the chemical reaction

:ATP + (4-amino-2-methylpyrimidin-5-yl)methyl phosphate ightleftharpoons ADP + (4-amino-2-methylpyrimidin-5-yl)methyl diphosphate

Thus, 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, specifically those transferring phosphorus-containing groups (phosphotransferases) with a phosphate group as acceptor. The systematic name of this enzyme class is ATP:(4-amino-2-methylpyrimidin-5-yl)methyl-phosphate phosphotransferase. Other names in common use include hydroxymethylpyrimidine phosphokinase, and ATP:4-amino-2-methyl-5-phosphomethylpyrimidine phosphotransferase. This enzyme participates in thiamine metabolism.
