Abstract:
TolC, a multifunctional outer membrane protein, creates a continuous conduit that extrudes substrates from the bacterial periplasm and the outer leaflet of the inner membrane to the external environment. TolC of Vibrio species functions as an outer membrane protein of multiple exporters, and is involved in antibiotic efflux, regulation and export of virulence factors, iron homeostasis, and survival under various extreme environments, thereby playing an indispensable role in the pathogenesis of Vibrio species. This review recapitulates the current knowledge about the functions and regulators of TolC homologous proteins in Vibrio species.

Protein Transport to the Outer Chloroplast Membrane
Two models describe the mechanism of precursor recognition and entry across the outer membrane through the TOC complex. Model 1 suggests the newly synthesized precursor binds to the TOC receptor 159 and forms a complex.

Surface Membrane Barriers
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...
Protein Transport to the Stroma
Protein complexes called the translocon of the outer chloroplast membrane or TOC complex, and the translocon of the inner chloroplast membrane or TIC complex mediate the...
