In enzymology a thiamine-diphosphate kinase is an enzyme involved in thiamine metabolism. It catalyzes the chemical reactionthiamine diphosphate + ATP thiamine triphosphate + ADPThus the two substrates of this enzyme are ATP and thiamine diphosphate whereas its two products are ADP and thiamine triphosphate.This enzyme belongs to the family of transferases specifically those transferring phosphorus-containing groups (phosphotransferases) with a phosphate group as acceptor.
