    The histidine-containing phosphocarrier protein (HPr) functions in the bacterial phosphoenolpyruvate:sugar phosphotransferase system (PTS). His15 on HPr accepts a phosphoryl group from Enzyme I and transfers it to the Enzyme IIA domain of a sugar-specific PTS permease. In addition, HPrs from Gram-positive bacteria undergo phosphorylation on a serine residue, Ser46, which inhibits phosphorylation at His15 and sugar transport. The questions to be addressed at the molecular level are: what is the mechanism of each of the phosphoryl transfers and what conformational transitions are associated with each event?
