Functional Family Phosphoenolpyruvate-protein phosphotransferase

Enzyme Information

2.7.3.9
Phosphoenolpyruvate--protein phosphotransferase.
based on mapping to UniProt P08839
Phosphoenolpyruvate + protein L-histidine = pyruvate + protein N(pi)- phospho-L-histidine.
-!- Acts only on histidine residues in specific phosphocarrier proteins of low molecular mass (9.5 kDa) involved in bacterial sugar transport. -!- A similar reaction where the protein is the enzyme EC 2.7.9.2 is part of the mechanism of that enzyme.
