1PCH - PubMed Abstract: 
The three-dimensional structures of histidine-containing phosphocarrier protein (HPr), a member of the phosphoenolpyruvate:sugar phosphotransferase system (PTS), have been determined from Gram-negative and Gram-positive bacteria. The structure of HPr reported here for Mycoplasma capricolum is the first protein structure to be determined for this class of organism. Comparative structural studies with the bacterial proteins highlight sequence-structure correlations relevant to proposals about the evolutionary origin of mycoplasmas.
