Short name: RNAP_delta_sf

Overlapping entries


This entry includes DNA-directed RNA polymerase subunit delta from Bacillus subtilis.

The delta protein is a dispensable subunit of Bacillus subtilis RNA polymerase (RNAP) that has major effects on the biochemical properties of the purified enzyme. In the presence of delta, RNAP displays an increased specificity of transcription, a decreased affinity for nucleic acids, and an increased efficiency of RNA synthesis because of enhanced recycling [PMID: 10336502]. The delta protein, contains two distinct regions, an N-terminal domain and a glutamate and aspartate residue-rich C-terminal region [PMID: 7545758]. It participates in both the initiation and recycling phases of transcription.
