AMR Gene: CARD Annotation CARD Database Homepage

Chains	Accession	Short Name	Description	Provenance Source (Version)
G [auth F], H [auth I], I [auth C]	ARO:3000237	TolC	TolC is a protein subunit of many multidrug efflux complexes in Gram negative bacteria. It is an outer membrane efflux protein and is constitutively open. Regulation of efflux activity is often at its periplasmic entrance by other components of the efflux complex.	CARD (4.0.1)
J [auth K], K [auth L], O [auth J]	ARO:3000216	acrB	Protein subunit of AcrA-AcrB-TolC multidrug efflux complex. AcrB functions as a herterotrimer which forms the inner membrane component and is primarily responsible for substrate recognition and energy transduction by acting as a drug/proton antiporter.	CARD (4.0.1)

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 alpha -helical hairpin domain of AcrA shows conformational flexibility, which has potential mechanistic significance in coupling between AcrA conformations and TolC channel opening [1].	Domain

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.	Domain

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]. Another member MexA, a Pseudomonas aeruginosa homolog of AcrA, is a component of the tripartite multidrug efflux system MexAB-OprM which is a major factor for antibiotic resistance by exporting a large variety of antimicrobial compounds [2]. The domain represented by this entry folds into an open barrel with a circularly permuted topology of SH3-like barrels. This domain is involved in interactions with efflux pump 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 [1,2]. 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.	Domain
