Constitutes, with BamD, the core component of the assembly machinery. Publication Abstract from PubMed In Escherichia coli, the BAM complex is employed to mediate correct folding of the outer membrane (OM) proteins into beta-barrels and their insertion into the OM. BamA, which is an essential component of the complex, consists of a C-terminal transmembrane region and five N-terminal polypeptide transport-associated (POTRA) domains. Although deletion studies have shown that each of the POTRA domains plays an important role in the process of BAM complex formation, only POTRA5 is essential for cell viability. Here, the crystal structure of POTRA4-5 has been determined to 1.50 A resolution with an R factor of 14.7% and an R(free) of 18.9%.
