Role of the alpha-helical linker of the C-terminal translocator in the biogenesis of the serine protease subfamily of autotransporters.

Abstract excerpt

Autotransporters are secreted virulence factors that comprise three domains: an N-terminal signal peptide, an internal passenger domain, and a C-terminal beta-domain. The mechanism of passenger translocation across the outer membrane remains undefined, with four models having been proposed: the "hairpin," the "threading," the "multimeric," and the "Omp85 (YaeT)" models. In an attempt to understand autotransporter...
