Figure 1 Cartoons Illustrating Models for the Assembly, Export, and Translocation of EPS and CPS to the Cell Surface Shown are the established ABC transporter-dependent (left) and Wzx-Wzy-dependent (right) pathways. To the right is a wire-frame representation (green) of the EM structure of the transenvelope translocation assembly from E. coli K30. The heterocomplex consists of a tetramer of the PCP-2a protein (Wzc) and an octamer of the OPX protein (Wza) (Collins et al., 2007). The Wza crystal structure (purple) and the EM structure of the Wzc tetramer (gold) have been manually fitted within the frame.
