The crystal structure of BamA, the central component of the β-barrel assembly machinery (BAM) complex, from N. gonorrhoeae and H. ducreyi is determined; the structure consists of an interior cavity capped by extracellular loops, an exterior rim with a narrowed hydrophobic surface and a lateral opening of the barrel domain, providing insight into a possible route for the insertion of β-barrel membrane proteins into the bacterial outer membrane.
