In enzymology a phosphoenolpyruvate-protein phosphotransferase (EC 2.7.3.9) is an enzyme that catalyzes the chemical reactionphosphoenolpyruvate + protein histidine pyruvate + protein Npi-phospho-L-histidineThus the two substrates of this enzyme are phosphoenolpyruvate and protein histidine whereas its two products are pyruvate and protein Npi-phospho-L-histidine.This enzyme belongs to the family of transferases specifically those transferring phosphorus-containing groups (phosphotransferases) with a nitrogenous group as acceptor.
