NameOMP chaperone system: SurA-Skp-DegP
DescriptionOuter membrane beta-barrel proteins are translocated into the periplasm by the Sec system and subsequently properly folded and inserted into the outer membrane by the beta-barrel assembly machine (Bam). In the periplasm chaperones prevent misfolding and aggregation and facilitate the transit across the periplasmic space. The SurA protein appears to be the primary chaperone, at least in E. coli [1], while Skp and DegP may act to rescue any OMPs which fall off of the SurA complex.
