2.7.3.9 | phosphoenolpyruvate + protein histidine = pyruvate + protein Npi-phospho-L-histidine |
enzyme I of the phosphotransferase system (cf. EC 2.7.1.69 protein-NĀ-phosphohistidine-sugar phosphotransferase), 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, pyruvate water dikinase, is part of the mechanism of that enzyme |

2.7.3.9 | phosphoenolpyruvate + protein histidine = pyruvate + protein Npi-phospho-L-histidine |
in a first reaction step phosphate is transferred to the N-3 position of the imidazole ring of histidine |
642504, 642508 |
2.7.3.9 | phosphoenolpyruvate + protein histidine = pyruvate + protein Npi-phospho-L-histidine |
in a second reaction step phosphate is transferred to the N-1 position of the imidazole ring of the histidine containing-protein (i.e. HPr), the phospho group of the intermediate phospho-enzyme I can also be transferred to pyruvate or 2-oxobutyrate |
