pubpic2015ccraneyWeidentify the S. aureus operon ayrRABC and show that once released from repression by AyrR, the protein products AyrABC together confer resistance to the SPase inhibitor arylomycin M131 by providing an alternate and novel method of releasing translocated proteins, and we demonstrate that AyrABC functionally complements SPase by mediating the processing of the normally secreted proteins. Overall, the data demonstrate that ayrRABC encodes a secretion stress-inducible alternate terminal step of the general secretory pathway.
