This entry represents the central domain of the PaaX protein which are transcriptional regulators of protein involved in metabolism of phenylacetic acid. This domain is structurally related to the Cas2 ribonuclease domain, suggesting that these proteins may degrade mRNAs to carry out regulation.	Domain
