Crystal Structure

Caption

A crystal structure of a gene-specific transcription activation complex reveals the interactions between RNA polymerase (black, gray, and green), sigma (yellow), and DNA (red and pink; sequence elements in violet and blue) that mediate DNA binding and DNA unwinding in transcription initiation and reveals the interactions between the transcription activator protein (TAP; light blue), RNA polymerase, and sigma that mediate transcription activation.
