Abstract
The crystal structure of the flavodoxin-like protein WrbA with oxidized FMN bound reveals a close relationship to mammalian NAD(P)H:quinone oxidoreductase, Nqo1. Structural comparison of WrbA, flavodoxin, and Nqo1 indicates how the twisted open-sheet fold of flavodoxins is elaborated to form multimers that extend catalytic function from one-electron transfer between protein partners using FMN to two-electron reduction of xenobiotics using FAD. The structure suggests a novel physiological role for WrbA and Nqo1.
