Omp85, an evolutionarily conserved bacterial protein involved in outer-membrane-protein assembly.

Abstract:

:The insertion of proteins into membranes generally requires the assistance of membrane proteins. A protein, designated Omp85 in Neisseria meningitidis, was shown to be required for the assembly of bacterial outer-membrane proteins. The protein is essential for the viability of the bacteria and is ubiquitous among Gram-negative bacteria. Omp85 depletion results in the accumulation of aggregates of unfolded outer-membrane proteins, and we argue that Omp85 is directly involved in outer-membrane-protein assembly. Omp85 shows sequence similarity with Toc75 of the chloroplast protein-import machinery, suggesting a common evolutionary origin.
