Escherichia coli K-12 substr. MG1655 Polypeptide: SdsRQP multidrug efflux transport system - predicted membrane fusion protein



Gene: mdtN Accession Numbers: EG11954 (EcoCyc), b4082, ECK4075

Synonyms: yjcR, sdsR

Regulation Summary Diagram: ?

Component of: SdsRQP multidrug efflux system (summary available)

Summary:
SdsR is predicted to be the membrane fusion protein component of the SdsRQP multidrug efflux pump [Dinh94, Shimada09]. An E. coli yjcR null mutant is more sensitive to sulfur drugs than wild type [Shimada09].

Subunit of: SdsRQP multidrug efflux system

Subunit composition of SdsRQP multidrug efflux system = [MdtP][MdtO][MdtN]
         SdsRQP multidrug efflux transport system - predicted outer membrane factor = MdtP (summary available)
         SdsRQP multidrug efflux transport system - uncharacterised component = MdtO (summary available)
         SdsRQP multidrug efflux transport system - predicted membrane fusion protein = MdtN (summary available)

Summary:
SdsRQP is a putative multidrug efflux pump involved in sulfur drug resistance [Shimada09]. An E.coli yjcR null mutant is more sensitive to sulfur drugs than wild type [Shimada09].
