How do outer membrane proteins (OMPs) make it from the interior of the cell, through the periplasm, and into the outer membrane? In Pseudomonas aeruginosa, Bam and Lol proteins are big helpers that get some, but not all, OMPs where they need to go. The authors of a study in mBio explain this spotty service may be due to individual differences in the membrane proteins. In short, some folks need the help more than others.
