Chains	Enzyme Name	Description	Catalytic Residues
A	phosphoenolpyruvate---protein phosphotransferase M-CSA #920	Phosphoenolpyruvate-protein phosphotransferase, (PTS enzyme I), is a component of the phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS). PTS catalyses the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. PTS enzyme I transfers the phosphoryl group from phosphoenolpyruvate to the phosphoryl carrier protein HPr [PMID:9922238].
