Is essential for fumarate respiration during anaerobic growth, acting as the terminal reductase (By similarity). Receives electrons from the membrane-bound tetraheme c-type cytochrome CymA (PubMed:12196158, PubMed:12899636, PubMed:19837833, PubMed:22458729). Under ferric iron-reducing conditions, can be part of an electron transport chain to ferric iron, by accepting electrons from CymA and transfering them to the c-type cytochrome MtrA (PubMed:19837833). Also plays an important role in the reduction of selenite to elemental selenium (PubMed:24435070). May act as a transient electron storage protein (PubMed:19837833).[UniProtKB:Q07WU7]<ref>PMID:12196158</ref> <ref>PMID:12899636</ref> <ref>PMID:19837833</ref> <ref>PMID:22458729</ref> <ref>PMID:24435070</ref> |

| + | Fumarate respiration is one of the most widespread types of anaerobic respiration. The soluble fumarate reductase of Shewanella putrefaciens MR-1 is a periplasmic tetraheme flavocytochrome c. The crystal structures of the enzyme were solved to 2.9 A for the uncomplexed form and to 2.8 A and 2.5 A for the fumarate and the succinate-bound protein, respectively. The structures reveal a flexible capping domain linked to the FAD-binding domain. A catalytic mechanism for fumarate reduction based on the structure of the complexed protein is proposed. The mechanism for the reverse reaction is a model for the homologous succinate dehydrogenase (complex II) of the respiratory chain. In flavocytochrome c fumarate reductase, all redox centers are in van der Waals contact with one another, thus providing an efficient conduit of electrons from the hemes via the FAD to fumarate. | ||
