trimethylamine-N-oxide reductase (cytochrome c) M-CSA #894 | Trimethylamine N-oxide (TMAO) has been found in a variety of marine organisms including fish, molluscs, crustaceans and seaweed [PMID:16221580]. TMAO is found in marine organisms as an osmolyte in combination with urea. In sharks, who lack a swim bladder, TMAO and urea contribute to buoyancy. A number of marine-fish spoilage organisms use TMAO as an electron acceptor in anaerobic respiration [PMID:3904597]. Trimethylamine (TMA), the volatile product of this reaction, has the specific odour of rotting fish. In Escherichia coli, the TMAO respiratory chain consists of a quinol electron donor, a membrane-bound multiheme c-type cytochrome TorC, and a periplasmic terminal reductase TorA that contains bis(molybdopterin guanine dinucleotide)molybdenum cofactor (this entry). This molybdoenzyme belongs to the dimethyl sulfoxide (DMSO) reductase family. | Defined by 2 residues: TRP:A-149 [auth A-118]SER:A-180 [auth A-149] | EC: 1.6.6.9 (PDB Primary Data) |
