Evolution of bacterial RNA polymerase: implications for large-scale bacterial phylogeny, domain accretion, and horizontal gene transfer.

Gene - 23 Jun 2004

Iyer Lakshminarayan M, Koonin Eugene V, Aravind L

Abstract excerpt

Comparative analysis of the domain architectures of the beta, beta', and sigma(70) subunits of bacterial DNA-dependent RNA polymerases (DdRp), combined with sequence-based phylogenetic analysis, revealed a fundamental split among bacteria. DNA-dependent RNA polymerase subunits of Group I, which includes Proteobacteria, Aquifex, Chlamydia, Spirochaetes, Cytophaga-Chlorobium, and Planctomycetes, are characterized...
