PrsA is a predicted extracellular membrane-bound peptidyl-prolyl cis-trans isomerase that is associated with tolerance to salt stress (53) and E. faecalis virulence in Galleria mellonella (53) and is upregulated in a rabbit subdermal abscess model (43), although no specific protein substrates for chaperone or foldase activity have been identified. This evidence concerns the gene GLRX5 and abscess.
