1.14.12.23 | native enzyme and in complex with nitrobenzene and 3-nitrotoluene, to 1.2 A, 1.55 A and 1.5 A resolution, respectively. Enzyme shows a mushroom-shaped alpha3beta3 hexamer. The catalytic subunit contains a Rieske iron-sulfur center and an active-site mononuclear iron atom. The substrate pocket contains an asparagine residue that forms a hydrogen bond to the nitro-group of the substrate, and orients the substrate in relation to the active-site mononuclear iron atom |
