    The phosphoenolpyruvate:sugar phosphotransferase system (PTS) is a bacterial and mycoplasma system responsible for the uptake of some sugars, concomitant with their phosphorylation. The sugar-specific component of the system, enzyme II (EII),consists of three domains, EIIA, EIIB and EIIC. EIIA and ELLB are cytoplasmic and EIIC is an integral membrane protein that contains the sugar-binding site. Phosphoenolpyruvate (PEP) provides the source of the phosphoryl group, which is transferred via several phosphoprotein intermediates, eventually being transferred to the internalized sugar. Along the pathway, EIIA accepts a phosphoryl group from the phosphocarrier protein HPr and transfers it to EIIB. The structure of the glucose-specific EIIA (EIIAglc) from Mycoplasma capricolum reported here facilitates understanding of the nature of the interactions between this protein and its partners.
