Figure 3.

Structural superimpositions of monomeric units for FabG. In this figure, the monomers of FabG from R. prowazekii (PDB entry 3f9i; purple helices, yellow strands), from E. coli (PDB entry 1i01; magenta), from M. tuberculosis (PDB entry 1uzm; light blue) and the NADP⁺-bound structure from V. cholerae (PDB entry 3rsk, pink) are superimposed. There is a significant structural variability between these structures in the proximity of the NADP⁺-binding site.
