Structural highlights The complex is composed of five subunits: BamA, BamB, BamC, BamD and BamE. Outer membrane β-barrel proteins assembly is dependent on Bam in various organisms. BamB,C,D,E bind to the N-terminal of BamA. BamA contains five structurally homologous POTRA (POlypeptide TRAnslocation associated) domains. The POTRA domain has a β-α-α-β-β conformation. BamA barrel and at least a subset of its POTRAs are essential for viability. BamA was found also in mitochondria and chloroplasts. BamD is composed of multiple tetratricopeptide (TPR) repeats packed into a superhelical structure. TPR is a motif containing 2 antiparallel α-helices. TPRs are found in scaffold multiprotein complexes and are involved in protein-protein interactions. 3D Structures of Bam complex Bam complex 3D structures
