Summary and future directions

Abstract

β-barrel outer membrane proteins (OMPs) are found in the outer membranes (OMs) of all gram-negative bacteria, yet exactly how they are folded and inserted remains unknown. The last decade has provided a wealth of discovery including the identification of the BAM complex, a multicomponent complex responsible for the biogenesis of all OMPs into the OM. It is anticipated that the next decade will further advance our knowledge of how the BAM complex is able to perform its unique and interesting function.
