Biology:PhrS
From HandWiki
PhrS is a bacterial small RNA found in Pseudomonas aeruginosa. It was first identified in a RNAomics screen and has since been found to act as a link between oxygen availability and quorum sensing.[1]
Synthesis of PhrS is dependent on the oxygen-responsive global regulator ANR, which is required for PhrS synthesis. The Hfq protein may also bind to PhrS.[2] In turn, PhrS regulates the transcriptional regulator PqsR which positively controls those genes involved in quorum sensing regulation in P. aeruginosa.
