In enzymology a 3-phosphoglyceroyl-phosphate—polyphosphate phosphotransferase (EC 2.7.4.17) is an enzyme that catalyzes the chemical reaction3-phospho-D-glyceroyl phosphate + (phosphate)n 3-phosphoglycerate + (phosphate)n+1Thus the two substrates of this enzyme are 3-phospho-D-glyceroyl phosphate and (phosphate)n whereas its two products are 3-phosphoglycerate and (phosphate)n+1.This enzyme belongs to the family of transferases specifically those transferring phosphorus-containing groups (phosphotransferases) with a phosphate group as acceptor.
