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 Cobalt-zinc-cadmium resistance protein CzcB and its paralogue Nickel and cobalt resistance protein CnrB from Cupriavidus metallidurans and related proteins. CzcB is a crucial component of the CzcCBA protein complex, which mediates heavy metal resistance in bacteria through an active cation efflux mechanism [1]. CzcB binds to CzcA, which in turn is bound to CzcC, forming the complete CzcCBA complex.
