Different thermal energy requirement for open complex formation by Escherichia coli RNA polymerase at two related promoters.

abstract：:During the splicing process, spliceosomal snRNAs undergo numerous conformational rearrangements that appear to be catalyzed by proteins belonging to the DEAD/H-box superfamily of RNA helicases. We have cloned a new RNA helicase gene, designated DBP2 (DEAH-boxprotein), homologous to the Schizosaccaromyces pombe cdc28(+...
