Gene type: protein coding
RefSeq status: PROVISIONAL
Organism: Escherichia coli str. K-12 substr. MG1655 (strain: K-12, substrain: MG1655)

Also known as: ECK1586; ynfI
Summary: dmsD is the fifth gene in the dmsABC-like operon ynfEFGH-dmsD. torD, dmsD and ycdY are paralogs.Overexpressed YdcY and DmsD interfere with apoTorA maturation by TorD, independent of the TorA signal peptide (Ilbert, 2004). [More information is available at EcoGene: EG13847]. DmsD binds to the twin-arginine leaders of certain proteins, including dimethylsulfoxide (DMSO) reductase and trimethylamine N-oxide (TMAO) reductase that are translocated to the cytoplasmic membrane for the periplasm by the Sec-independent system that is termed Mtt (membrane targeting and transport) or more frequently Tat (twin-arginine translocation) . [More information is available at EcoCyc: G6849].
