Cloned(Commentary)

EC Number Cloned (Comment) Organism
1.7.2.3 amplification of the structural torA gene encoding the enzyme and iits flanking regions using PCR techniques, the torA gene is the third gene of a TMAO-inducible operon, torECAD, encoding the TMAO respiratory components, the torC gene encodes a pentahemic c-type cytochrome, likely to be involved in electron transfer to the TorA terminal reductase, the role of the torE gene is unknown, torD gene encodes the TorD protein, a cytoplasmic protein involved in the folding process of the TorA precursor protein Shewanella massilia
