Cotranslational Translocation and Folding of a Periplasmic Protein Domain in Escherichia coli.

Abstract excerpt

In Gram-negative bacteria, periplasmic domains in inner membrane proteins are cotranslationally translocated across the inner membrane through the SecYEG translocon. To what degree such domains also start to fold cotranslationally is generally difficult to determine using currently available methods. Here, we apply Force Profile Analysis (FPA) - a method where a translational arrest peptide is used to detect...
