In enzymology a thiamine-phosphate diphosphorylase (EC 2.5.1.3) is an enzyme that catalyzes the chemical reaction2-methyl-4-amino-5-hydroxymethylpyrimidine diphosphate + 4-methyl-5-(2-phosphono-oxyethyl)thiazole diphosphate + thiamine phosphateThus the two substrates of this enzyme are 2-methyl-4-amino-5-hydroxymethylpyrimidine diphosphate and 4-methyl-5-(2-phosphono-oxyethyl)thiazole whereas its two products are diphosphate and thiamine phosphate.This enzyme belongs to the family of transferases specifically those transferring aryl or alkyl groups other than methyl groups.
