Notizen: Abstract The essential role of DNA-dependent RNA polymerases in gene expression and the fact that the multimeric species are highly conserved throughout nature makes these enzymes a particular fascinating area of study. Here we shall review the conservation of structures and their relationship to function, especially in the multimeric eubacterial RNA polymerases, paying particular attention to the β core subunit and to recent studies of σ-factors of both the σ 70 and σ 54 families. We shall conclude with a brief consideration of phage-encoded RNA polymerases and phage-mediated modification of the host enzyme, and of the evolution of RNA-synthesising enzymes.
