Abstact

The dominant transcriptional regulator of the papillomaviruses, E2, binds to its specific DNA target through a previously unobserved dimeric antiparallel beta-barrel. The DNA is severely but smoothly bent over the barrel by the interaction of successive major grooves with a pair of symmetrically disposed alpha-helices. The specific interface is an 'interwoven' network of interactions where the identifying base pairs of the target contact more than one amino-acid side chain and the discriminating amino acids interact with more than one base pair.
