Abstract

The mechanisms by which RNA polymerase moves along DNA during elongation have been difficult to determine experimentally. In this issue of Cell, Bar-Nahum et al. (2005) show that back and forth sliding of RNA polymerase on DNA may be coupled to bending of an α helix, which can alternately occlude and expose the NTP binding site. Transcription factors can regulate elongation by modulating this bending motion.
