Fig. 1. Schematic presentation of ATP- and PEP-dependent HPr phosphorylation. The ATP-dependent phosphorylation of HPr by HprK/P at Ser46 is stimulated by FBP, whereas dephosphorylation of P-Ser-HPr is activated by Pi. Within the PTS phosphorylation cascade, HPr is phosphorylated intermediately by EI at His15 and transfers its phosphoryl group to various EIIAs.
