2.A.1.3.24
The VceAB multidrug (hydrophobic compounds including deoxycholate (DOC), antibiotics, such as chloramphenicol and nalidixic acid, and the proton motive force uncoupler, cyanide carbonyl m-chlorophenylhydrazone (CCCP)) resistance pump (functions with outer membrane VceC (TC#1.B.17.3.6) or OprM (2.A.6.2.21), an OMF family member; The C-terminal domain of the Pseudomonas aeruginosa OprM and the alpha-helical hairpin domain of Vibrio cholerae VceA play important roles in recognition/specificity/recruitment in the assembly of a functional, VceAB-OprM chimeric efflux pump (Bai et al., 2010).
