pubpic2012schallenbergerWe use an arylomycin as a probe of protein secretion to identify forty-six proteins whose extracellular accumulation in S. aureus requires the activity of signal peptidase (SPase). These include a wide variety of virulence proteins with identifiable Sec-type signal peptides, as well as some proteins with non-canonical cleavage sites.
