The DmsC polypeptide is composed of eight segments of hydrophobic amino acids of appropriate length to cross the cytoplasmic membrane, suggesting that this subunit functions to anchor the DMSO enzyme to the membrane.

PMID: 11389150 The hydrophobic region of the DmsA twin-arginine leader peptide determines specificity with chaperone DmsD. PMID: 24093457 Fluorescence analysis of these YFP chimeras revealed a wide range of interactions such as the one between the Tat substrate dimethyl sulfoxide reductase (DmsA) and its dedicated proofreading chaperone DmsD.

b0997 JW0982 periplasmic protein (TAT through IM), Trimethylamine-N-oxide reductase 1 TorAPeriplasmicTAT secretion system. Trimethylamine N-oxide (TMAO) respiration system is encoded by the torCAD operon and comprises a periplasmic TMAO reductase (TorA) and a c-type cytochrome (TorC), which shuttles electrons to TorA. Interaction studies showed that, when immature, TorC can no longer bind TorA efficiently but can bind the periplasmic detector region of sensor TorS. Electron transfer and binding of the c-type cytochrome TorC to the trimethylamine N-oxide reductase TorD, a cytoplasmic chaperone that interacts with the unfolded trimethylamine N-oxide reductase enzyme (TorA). The absence of TorD protein leads to a two times decrease of the final amount of TorA enzyme.
