RtcR DNA-binding transcriptional activator

Synonyms: RtcR
RtcR , "RNA terminal phosphate cyclase regulator," regulates the expression of genes involved in the ATP-dependent conversion of a 3'-phosphate at the end of RNA to 2',3'-cyclic phosphodiester [1] RtcR belongs to the group of σ54-dependent transcriptional regulators, which contain three domains: the sensory domain located in the N terminus, the central domain involved in ATP hydrolysis and interaction with σ54, and the C-terminal domain, which contains a helix-turn-helix motif. Although the C-terminal domain and the central domain from RtcR are similar to those of other members of this group, its N-terminal domain is not [1] The rtcR gene is transcribed divergently from the genes it regulates [1]
