Figure 6.

Alignment of Wzt^O9a-C (residues 270–423) to Wzt^O7-C (residues 303–455). A, pairwise sequence alignment was performed by Blast (A). The indicated secondary structure elements are from the Wzt^O9a-C crystal structure (Protein Data Bank entry 2R5O) and a Phyre² model of Wzt^O7-C. The residues coloured red are important for O-PS binding by Wzt^O9a-C (23). B, cartoon representation overlay of Wzt^O7-C model (orange) with Wzt^O9a-C crystal structure (blue). The structural overlay was generated using PyMOL (Schrödinger, LLC).
