'''Phosphocarrier protein HPr''' (HPr) is a component of the sugar phosphotransferase system. The system catalyses the phosphorylation of sugars during their translocation across cell membrane. A phosphoryl group is transferred from phosphoenolpyruvate via several enzymes (EI, EII) to HPr<ref>PMID:8246840</ref>. A conserved histidine in the N terminal of HPr is the acceptor of the phosphate. In Gram-positive bacteria HPr there is a conserved serine which is phosphorylated. | '''Phosphocarrier protein HPr''' (HPr) is a component of the sugar phosphotransferase system.
