Protein Family Models

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]. [1]. 9694879. SecDF of Bacillus subtilis, a molecular Siamese twin required for the efficient secretion of proteins. Bolhuis A, Broekhuizen CP, Sorokin A, van Roosmalen ML, Venema G, Bron S, Quax WJ, van Dijl JM;. J Biol Chem 1998;273:21217-21224. [2]. 8112309. SecD and SecF are required for the proton electrochemical gradient stimulation of preprotein translocation. Arkowitz RA, Wickner W;. EMBO J 1994;13:954-963. (from Pfam)

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;.
