In enzymology a thiamine diphosphokinase (EC 2.7.6.2) is an enzyme that catalyzes the chemical reactionATP + thiamine AMP + thiamine diphosphateThus the two substrates of this enzyme are ATP and thiamine whereas its two products are AMP and thiamine diphosphate.This enzyme belongs to the family of transferases specifically those transferring two phosphorus-containing groups (diphosphotransferases). The systematic name of this enzyme class is ATP:thiamine diphosphotransferase.
