Part of the outer membrane protein assembly complex (Bam), which is involved in assembly and insertion of beta-barrel proteins into the outer membrane. Constitutes, with BamD, the core component of the assembly machinery. Efficient substrate folding and insertion into the outer membrane requires all 5 subunits (PubMed:20378773, PubMed:21823654, PubMed:27686148).

A lateral gate may open between the first and last strands of the BamA beta-barrel that allows substrate to insert into the outer membrane; comparison of the structures of complete and nearly complete Bam complexes show there is considerable movement of all 5 proteins (PubMed:27686148, PubMed:26900875, PubMed:26901871, PubMed:26744406).

(Microbial infection) Acts as a receptor for CdiA-EC93, the contact-dependent growth inhibition (CDI) effector of E.coli strain EC93; antibodies against extracellular epitopes decrease CDI. Its role in CDI is independent of the other Bam complex components (PubMed:18761695).

Is not the receptor for CdiA from E.coli strain 536 / UPEC, which does not have the same mode of toxicity as CdiA from strain EC93; the decreased expression of bamA101 in some experiments decreases the level of outer membrane proteins in general (PubMed:23469034, PubMed:23882017).

Susceptibility to CdiA-EC93 is dependent on E.coli BamA; replacing BamA with the gene from S.typhimurium LT2, E.cloacae ATCC 13047 or D.dadantii 3937 renders cells resistant to CdiA-EC93. Cells with BamA from another bacteria no longer form CdiA-EC93-induced aggregates with EC93 cells. A chimera in which E.cloacae extracellular loops 6 and 7 are replaced with loops 6 and 7 from E.coli is susceptible to CdiA-EC93 and to CdiA-CT from strain 536 / UPEC (PubMed:23882017).

Deletion is lethal. Depletion results in the accumulation of incorrectly assembled outer membrane proteins, including TolC, OmpF, OmpC and OmpA (PubMed:15851030, PubMed:16102012). Decreased expression leads to decreased susceptibility to contact-dependent growth inhibition (CDI), and decreased expression of outer membrane proteins (including in this study LamB) as well as up-regulation of periplasmic protease DegP (PubMed:18761695, PubMed:23469034).4 Publications

Contains 5 N-terminal periplasmic polypeptide transport-associated (POTRA) domains which interact with other subunits of the complex, may recruit substrates from the periplasm into the outer membrane and also act as a chaperone (PubMed:17702946, PubMed:18430136, PubMed:19081063, PubMed:21795783, PubMed:14559180). The C-terminal region forms a discontinuous 16-stranded beta-barrel transmembrane region. The central pore is ellipsoid, and probably closed by extracellular loop 6, perhaps with the aid of other loops (PubMed:24914988, PubMed:24619089).1 Publication6 Publications

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:iDDCE4C6D341664EB
