Regulation of the intercellular adhesin locus regulator (icaR) by SarA, sigmaB, and IcaR in Staphylococcus aureus.

Abstract excerpt

The staphylococcal accessory regulator SarA and the alternative sigma factor sigma(B) have been previously identified as positive regulators, and IcaR as a negative regulator, of icaADBC expression. Here, we show that in Staphylococcus aureus SarA and sigma(B) are also required for icaR expression and that IcaR does not have a significant effect on its own expression.
