<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Part of the outer membrane protein assembly complex (Bam), which is involved in assembly and insertion of beta-barrel proteins into the outer membrane. Nonessential member of the complex that stabilizes the interaction between the essential proteins BamA and BamD. May modulate the conformation of BamA, likely through interactions with BamD. 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).10 Publications
