| Authors: | J E Anderson M Ptashne S C Harrison |
| Abstract: | The crystal structure of a complex between the DNA-binding domain of phage 434 repressor and a synthetic 434 operator shows that the protein, very similar in conformation to gamma repressor, binds to B-form DNA with the second alpha-helix of a helix-turn-helix motif lying in the major groove. |
