Fig. 1. The overall structure of Fd-GltS with the
N-terminal amidotransferase domain depicted in cornflower blue,
the FMN-binding domain in yellow, the central domain in magenta,
and the C-terminal domain in green. The FMN cofactor and the
3Fe-4S cluster are shown in black ball-and-stick, and the
ammonia channel is outlined by red spheres. Dashed lines connect
the borders of disordered loops.
