Protein Family Models

Members of this family are putative integral membrane proteins from bacteria. Several of the members are mycobacterial proteins. Many of the proteins contain two copies of this aligned region. The function of these proteins is not known, although it has been suggested that they may be involved in lipid transport [1]. [1]. 10694977.

This family consists of various prokaryotic SecD and SecF protein export membrane proteins. This SecD and SecF proteins are part of the multimeric protein export complex comprising SecA, D, E, F, G, Y, and YajC [1]. SecD and SecF are required to maintain a proton motive force [2].

Members of this family are integral membrane proteins. Some are involved in drug resistance. AcrB cooperates with a membrane fusion protein, AcrA, and an outer membrane channel TolC. The structure shows the AcrB forms a homotrimer [1]. [1]. 12374972. Crystal structure of bacterial multidrug efflux transporter AcrB. Murakami S, Nakashima R, Yamashita E, Yamaguchi A;.
