摘要：

RNA polymerases (RNAPs) are core components of the cellular transcriptional machinery. Progress with functional studies of eukaryotic RNAPs has been delayed by the fact that it has not yet been possible to assemble active enzymes from individual subunits. Archaeal RNAPs are directly comparable to eukaryotic RNAPII in terms of primary sequence homology and quaternary structure. Here we report the successful in vitro assembly of a recombinant archaeal RNAP from purified subunits. The recombinant enzyme displays full activity in transcription assays and is capable, in the presence of two other basal factors, of promoter-specific transcription. The assembly of mutant enzymes yielded several unexpected insights into the structural and functional contributions of various subunits toward overall RNAP activity.
