Contribution of the Twin Arginine Translocation system to the exoproteome of Pseudomonas aeruginosa.

ABSTRACT: The opportunistic pathogen Pseudomonas aeruginosa uses secretion systems to deliver exoproteins into the environment. These exoproteins contribute to bacterial survival, adaptation, and virulence. The Twin arginine translocation (Tat) export system enables the export of folded proteins into the periplasm, some of which can then be further secreted outside the cell. However, the full range of proteins that are conveyed by Tat is unknown, despite the importance of Tat for the adaptability and full virulence of P. aeruginosa. In this work, we explored the P. aeruginosa Tat-dependent exoproteome under phosphate starvation by two-dimensional gel analysis. We identified the major secreted proteins and new Tat-dependent exoproteins. These exoproteins were further analyzed by a combination of in s
