RNAIII

RNAIII

RNAIII is a non-coding RNA which is known to regulate the expression of many "Staphylococcus aureus" genes encoding exoproteins and cell wall associated proteins. In "S. aureus", RNAIII acts as the effector of the agr quorum sensing system and is transcribed from the P3 operon. The RNAIII transcript also contains the 26 amino acid delta-haemolysin gene (hld).
