emrB is a translocase in the emrB -TolC efflux protein in E. coli. It recognizes substrates including carbonyl cyanide m-chlorophenylhydrazone (CCCP), nalidixic acid, and thioloactomycin.

This domain is found in the AaeA protein which is a component of the p-hydroxybenzoic acid (pHBA) efflux pump in Escherichia coli [1] and related proteins. AaeA forms an efflux pump with AaeB, which functions to export certain aromatic carboxylic acids from the cell. The AaeAB efflux system serves as a 'metabolic relief valve' to alleviate toxic effects of imbalanced metabolism by eliminating specific compounds when they accumulate to high levels in the cell [1]. The domain represented in this entry folds into a six-stranded closed beta-barrel with a greek-key topology which has a structural similarity to the C-terminal domain of alanine racemase. This domain is interrupted by the barrel-sandwich hybrid domain which is inserted after the first beta-strand of the barrel. This model does not include the N-terminal strand.

This domain is found in the Multidrug export protein EmrA and related proteins, including its paralogue ErmK. EmrA is a crucial component of the EmrAB-TolC efflux system in Escherichia coli, which plays a significant role in conferring resistance to various antibiotics and toxic compounds [1,2]. This protein bridges the inner membrane transporter EmrB and the outer membrane channel TolC and thus facilitates the export of substances across both membranes.
This domain is found in the periplasmic membrane fusion proteins (MFPs) that are components of the RND tripartite drug efflux pumps. MFPs bridge the outer membrane factor and an inner membrane transporter. The most characterized MFP AcrA connects the ...
This domain is found in the periplasmic membrane fusion proteins (MFPs) that are components of the RND tripartite drug efflux pumps. MFPs bridge the outer membrane factor and an inner membrane transporter. The most characterized MFP AcrA connects the outer membrane factor TolC and the resistance-nodulation-division-type efflux transporter AcrB, which is a major multidrug efflux pump in Escherichia coli [1]. The barrel-sandwich hybrid domain is an important structural feature found in membrane fusion proteins. This domain plays a crucial role in the assembly and function of tripartite drug efflux systems [2]. It is involved in interactions with the other components of the RND pumps.
