Summary:
In the anaerobic respiratory chain formed by NADH dehydrogenase I (NDH-1) and trimethylamine N-oxide (TMAO) reductase the transfer of electrons from NADH to TMAO is coupled to the generation of a proton-motive force across the cytoplasmic membrane [Cox80].

By analogy to the related enzyme from mitochondria, NDH-I is thought to function as a proton pump translocating 4H+ per NADH oxidised (2e-) [H+/e- = 2] however a lower ratio of 3H+/2e- has also been proposed [Bogachev96, Wikstrom12]. TMAO reductase does not contribute to proton potential and thus proton pumping by NDH-I is the only mechanism for proton motive force (PMF) generation in anaerobic NADH → TMAO respiration (see review by [Simon08]. Menaquinone (shown here) or demethylmenaquinone serves as the redox mediator during anaerobic respiration with TMAO [Wissenbach90, Wissenbach92].

In addition to the inducible TMAO reductase encoded by torCA (shown here), E. coli K-12 contains a second TMAO reductase encoded by torYZ. torYZ has low constitutive expression and is not induced by TMAO or dimethyl sulfoxide [Gon00]. TorAC is an inducible TMAO reductase and is expressed in both anaerobic and aerobic conditions [Ansaldi07]. The DMSO reductase, DmsABC, is also able to reduce TMAO.

Many early studies on anaerobic TMAO respiration were done using E. coli K-10 [Takagi81, Shimokawa79].
