part of periplasmic side of cell outer membrane membrane protein complex extracellular protein-containing complex Bam protein complex https://github.com/geneontology/go-ontology/issues/31720 GO:1990063 bhm 2013-03-20T15:42:57Z Protein complex which is involved in assembly and insertion of beta-barrel proteins into the outer membrane. In E. coli it is composed of BamABCDE, of the outer membrane protein BamA, and four lipoproteins BamB, BamC, BamD and BamE. BamA interacts directly with BamB and the BamCDE subcomplex.
