Asymmetric/Biological Unit(hide GO term definitions)
Chain A,B,C,D   (BAMB_ECOLI | P77774)
molecular function
    GO:0042802    identical protein binding    Interacting selectively and non-covalently with an identical protein or proteins.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
biological process
    GO:0043165    Gram-negative-bacterium-type cell outer membrane assembly    The assembly of an outer membrane of the type formed in Gram-negative bacteria. This membrane is enriched in polysaccharide and protein, and the outer leaflet of the membrane contains specific lipopolysaccharide structures.
    GO:0051205    protein insertion into membrane    The process that results in the incorporation of a protein into a biological membrane. Incorporation in this context means having some part or covalently attached group that is inserted into the the hydrophobic region of one or both bilayers.
cellular component
    GO:1990063    Bam protein complex    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.
    GO:0009279    cell outer membrane    A lipid bilayer that forms the outermost membrane of the cell envelope; enriched in polysaccharide and protein; the outer leaflet of the membrane contains specific lipopolysaccharide structures.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
