title: Purification of DNA-Dependent RNA Polymerase from Eubacteria.
abstract: In eubacteria, the structure of DNA-dependent RNA polymerase is conserved; the enzyme is composed of at least four different subunits: beta (β), beta-prime (β'), and alpha (α), which form the core (ββ'α(2)), and sigma (σ), which is required for efficient promoter selection (1-3).
