Escherichia coli K-12 substr. MG1655 Polypeptide: RtcR DNA-binding transcriptional activator



Gene: rtcR Accession Numbers: EG12356 (EcoCyc), b3422, ECK3408

Synonyms: yhgB

Regulation Summary Diagram: ?

Summary:
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 [Genschik98].

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 [Genschik98].

The rtcR gene is transcribed divergently from the genes it regulates [Genschik98].
