Folding of a bacterial integral outer membrane protein is initiated in the periplasm

The Bam complex promotes the insertion of β-barrel proteins (such as UpaG, a trimeric autotransporter adhesin) into the bacterial outer membrane. Here, Sikdar et al. show that UpaG β-barrel segments fold into a trimeric structure in the periplasm before they interact with the Bam complex.
