The crystal structure of the DNA-binding domain of bacteriophage 434 repressor (R1-69) in complex with a 20 base-pair DNA fragment has been determined to 2.5 A resolution. The DNA fragment contains the sequence of the OR2 operator site, which differs from the previously studied OR1 site at three of the variable six central base-pairs ...
