Abstract excerpt
Crh of Bacillus subtilis exhibits 45% sequence identity when compared to histidine-containing protein (HPr), a phosphocarrier protein of the phosphoenolpyruvate (PEP):sugar phosphotransferase system (PTS). Crh can be phosphorylated by ATP at the regulatory Ser-46 and similar to P-Ser-HPr, P-Ser-Crh plays a role in carbon-catabolite repression. The sequence around the phosphorylatable Ser-46 in Crh exhibits strong...
