Regulator of RNA terminal phosphate cyclase RtcR is a sigma54-dependent enhancer binding protein that activates transcription of the rtcBA operon. The product of the rtcA gene is an RNA 3'-terminal phosphate cyclase. This domain is found at the N terminus of the RtcR sequence. RtcR, and other sigma54-dependent activators, contain pfam00158 in the central region of the protein sequence. |
