This entry represents transcriptional regulatory proteins in Staphylococcal species including SarA and Rot [1-5]. Sar is a global regulator with both positive and negative effects that controls expression of several virulence factors and biofilm formation process in a cell density-dependent manner. Rot plays a key role in regulating S. aureus virulence through activation or repression of promoters that control expression of a large number of critical virulence factors [5].	Domain
