The transcriptional regulator ArcR represses virulence and γ-hemolysin expression in Staphylococcus aureus USA300 LAC.
Staphylococcus aureus is a major opportunistic pathogen responsible for a wide range of infections, and its pathogenicity is tightly controlled by regulatory networks linking metabolism and virulence. ArcR, a member of the Crp/Fnr family that regulates the arginine deiminase (ADI) pathway, has an unclear role in coordi...
