The Two α Subunits of Escherichia coli RNA Polymerase are Asymmetrically Arranged and Contact Different Halves of the DNA Upstream Element
RNA polymerase core enzyme of Escherichia coli is composed of two α subunits and one each of the β and β ′ subunits. The C-terminal domain of the RNA polymerase α subunit plays a key role in molecular communications with class I transcription factors and upstream (UP) elements of promoter DNA, using...
