PubMed Abstract: Streptococcus pneumoniae harbors a significant number of transporters, including phosphotransferase (PTS) systems, allowing the bacterium to utilize a number of different carbohydrates for metabolic and other purposes. The genes encoding for one PTS transport system in particular (EII ) are found within a fucose utilization operon in S. pneumoniae TIGR4. Here, we report the three-dimensional structures of IIA and IIB providing evidence that this PTS system belongs to the EII family. Additionally, the predicted metabolic pathway for this distinctive fucose utilization system suggests that EII transports the H-disaccharide blood group antigen, which would represent a novel PTS transporter specificity.
