Skp, a molecular chaperone of gram-negative bacteria, is required for the formation of soluble periplasmic intermediates of outer membrane proteins.

Abstract excerpt

Using a cross-linking approach, we have analyzed the function of Skp, a presumed molecular chaperone of the periplasmic space of Escherichia coli, during the biogenesis of an outer membrane protein (OmpA). Following its transmembrane translocation, OmpA interacts with Skp in close vicinity to the plasma membrane. In vitro, Skp was also found to bind strongly and specifically to pOmpA nascent chains after their...
