Superfamily: RNA polymerase II/Efflux pump adaptor protein, barrel-sandwich hybrid domain

This superfamily comprises a barrel-sandwich hybrid domain, also known as the sandwich-barrel hybrid motif (SBHM), which is found in a variety of protein structures. Members of this superfamily include the lipoyl and biotinyl domains from adaptor/membrane fusion proteins from the RND (resistance nodulation cell division) family of bacterial efflux pumps (such as BesA, MexA, AcrA, EmrA, CusB, ZneB and MacA), the SBHM domain from the beta subunit in DNA-dependent RNA polymerases (such as in Escherichia coli Ec-beta and Thermus aquaticus Taq-beta), V-type ATP synthases, and ribosomal protein L27.
