Abstract
Control of RNA polymerase is a common means of regulating gene expression. A detailed picture of both the structure and how the structural details of RNA polymerase encode function is a key to understanding the molecular strategies used to regulate RNA polymerase. We review here data which ascribes functons to some regions of the primary sequence of the subunits (α,ββ'σ) which make up
E. coli
RNA polymerase. We review both genetic and biochemical data which place regions of the primary sequence that are distant from one another in close proximity in the tertiary structure. Finally we discuss the implications of these findings on the quaternary structure of RNA polymerase.
