In enzymology a triphosphate-protein phosphotransferase (EC 2.7.99.1) is an enzyme that catalyzes the chemical reactiontriphosphate + [microsomal-membrane protein] diphosphate + phospho-[microsomal-membrane protein]Thus the two substrates of this enzyme are triphosphate and microsomal-membrane protein whereas its two products are diphosphate and [[phospho-[microsomal-membrane protein]]].This enzyme belongs to the family of transferases specifically those transferring phosphorus-containing groups that are not covered by other phosphotransferase families.
