Crystal structure of /E. coli/ protein WrbA holoprotein to 2.6 and 2.0 Å resolution, and WrbA apoprotein to 1.85 Å, are refined and analysed comparatively through the lens of flavodoxin structures. The results indicate that differences between apo- and holoWrbA crystal structures are manifested on many levels of protein organization as well as in the FMN-binding sites. Structural changes upon cofactor binding are compared with the monomeric flavodoxins. Analysis of the three crystal structures described here, together with flavodoxin structures, rationalizes functional similarities and differences of the WrbAs relative to flavodoxins, leading to a new understanding of the defining features of WrbAs.
