Interaction of SecB with intermediates along the folding pathway of maltose-binding protein.

Protein science : a publication of the Protein Society - 1 Jun 1995

Diamond D L, Strobel S, Chun S Y, Randall L L

Abstract excerpt

SecB, a molecular chaperone involved in protein export in Escherichia coli, displays the remarkable ability to selectively bind many different polypeptide ligands whose only common feature is that of being nonnative. The selectivity is explained in part by a kinetic partitioning between the folding of a polypeptide and its association with SecB. SecB has no affinity for native, stably folded polypeptides but...
