Here, using in vitro and in vivo protein-DNA ...

Webbtransitions between an open and a closed state in order to extrude loops by a scrunching mechanism, similar to that proposed in DNA bubble formation during bacterial transcription. Changes in the orientation of the motor domains are transmitted over ˘ 50 nm, connecting the motor head and the hinge, thus providing an allosteric basis for LE.

WebbOur current work extends published studies where, in collaboration with Shimon Weiss (UCLA) and Richard Ebright (Rutgers), we showed that σ70 is not released upon escape to elongation (2); identified the rate-limiting step of abortive initiation (3); and showed that abortive initiation mainly proceeds through a DNA-scrunching mechanism (4,5).

WebbIt has long been known that during initial transcription of the first 8–10 bases of RNA, complexes are relatively unstable, leading to the release of short abortive RNA transcripts. An early “stressed intermediate” model led to a more specific mechanistic model proposing “scrunching” stress as the basis for the instability.
