X-ray crystal structure of Escherichia coli RNA polymerase σ70 holoenzyme.

Abstract excerpt

Escherichia coli RNA polymerase (RNAP) is the most studied bacterial RNAP and has been used as the model RNAP for screening and evaluating potential RNAP-targeting antibiotics. However, the x-ray crystal structure of E. coli RNAP has been limited to individual domains. Here, I report the x-ray structure of the E. coli RNAP σ(70) holoenzyme, which shows σ region 1.1 (σ1.1) and the α subunit C-terminal domain for...
