Structures of MMO components and proposed reaction cycle. A) MMOH, B) the MMOR FAD and ferredoxin (Fd) domains, and C) MMOB. The MMOH α, β, and γ subunits are colored blue, green, and purple, respectively. Iron, sulfur, and FAD are colored orange, yellow, and red, respectively, and are depicted as spheres. The MMO reaction cycle is shown on the right with atoms colored according to type [iron (black), carbon (gray), oxygen (red), and nitrogen (blue)].
