Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image   Print3D Flavocytochrome c or flavocytochrome c sulphide dehydrogenase or Fcc catalyzes the conversion of H2S and ferricytochrome c to S and ferrocytochrome c. Fcc3 has fumarate reductase activity Flavocytochrome b2 is a L-lactate/cytochrome c oxidoreductase Flavocytochrome b558 is the catalytic component of the phagocyte NADPH oxidase Structure of heme-containing flavocytochrome c3 complex with FAD and fumaric acid (PDB code 2b7r). 1st Heme binding site. Water molecules are shown as red spheres. 1st Heme Fe coordination site. 2nd Heme binding site. 2nd Heme Fe coordination site. 3rd Heme binding site. 3rd Heme Fe coordination site. 4th Heme binding site. 4th Heme Fe coordination site. Interestedly, that all 4 heme groups are covalently bound with Cys residues in heme-containing flavocytochrome c3 (PDB code 2b7r). All Fe of 4 heme groups are coordinated with His residues.
