---|---|---|---|---|---|---|
phosphoenolpyruvate + protein histidine | the phosphoryl group is transferred from phosphoenolpyruvate to the enzyme and to a low molecular weight phosphocarrier protein, phosphorylation rate of the enzyme increases at presence of the phosphorylated phosphocarrier protein, phosphoryl group transfer proceeds in 4 reactions | Escherichia coli | pyruvate + protein N-pros-phosphohistidine | - |
