Figure 2. Structure of P. aeruginosa NanPs.
A. The β-strands are shown in green, α-helices in yellow, and connecting loops in magenta. B. Molecular surface of NanPs in the active site region, colored by electrostatic potential. The view is the same as that of Figure 1D, and the position of NANA bound to NanA is shown for reference. C. Structural differences between the active site regions NanPs (in green) and NanA (in cyan). Residue numbers in green are for NanPs, and those in blue for NanA.
