Transcription initiation site selection and abortive initiation cycling of phage SP6 RNA polymerase.

Effects of mutations around the phage SP6 transcription initiation site on SP6 RNA polymerase's selection of initiation site were studied. In the in vitro transcription reactions, the limiting concentration of a ribonucleotide causes the SP6 RNA polymerase to stall long enough only at the positions of the limited nucleotide and dissociate from the elongation complex. As a result, a series of RN...

Snapshots of RNA polymerase II transcription initiation.

Several papers published within the last year utilize innovative techniques for characterizing intermediates in RNA polymerase II transcription. Structural studies of polymerase and its associated factors provide a detailed picture of the transcription machinery, and studies of transcription complex assembly both in vitro and in vivo provide insights into the mechanism of gene expression. A hig...

Abortive initiation and productive initiation by RNA polymerase involve DNA scrunching.

Using single-molecule DNA nanomanipulation, we show that abortive initiation involves DNA "scrunching"--in which RNA polymerase (RNAP) remains stationary and unwinds and pulls downstream DNA into itself--and that scrunching requires RNA synthesis and depends on RNA length. We show further that promoter escape involves scrunching, and that scrunching occurs in most or all instances of promoter e...

Transcription Start Site Scanning and the Requirement for ATP during Transcription Initiation by RNA Polymerase II.

Saccharomyces cerevisiae RNA polymerase (Pol) II locates transcription start sites (TSS) at TATA-containing promoters by scanning sequences downstream from the site of preinitiation complex formation, a process that involves the translocation of downstream promoter DNA toward Pol II. To investigate a potential role of yeast Pol II transcription in TSS scanning, HIS4 promoter derivatives were ge...

An archaebacterial RNA polymerase binding site and transcription initiation of the hisA gene in Methanococcus vannielii

Transcription initiation of the hisA gene in vivo in the archaebacterium Methanococcus vannielii, as determined by nuclease S1 and primer extension analyses, occurs 73 base pairs (bp) upstream of the translation initiation site. Binding of M. vannielii RNA polymerase protects 43 bp of DNA, from 35 bp upstream (-35) to 8 bp downstream (+8) of the hisA mRNA initiation site, from digestion by DNas...
