Crystallization of a complex of cro repressor with a 17 base-pair operator.

Journal Article (Journal Article)

Crystals of the lambda cro repressor complexed to a 17 base-pair synthetic binding site related to the OR3 operator have been obtained. The complex crystallizes in the hexagonal space group P6(2) (or P6(4)) with unit cell dimensions a = b = 154.8 A, c = 85.6 A. Preliminary photography reveals that the crystals are stable to X-rays and display measurable reflections to a resolution of about 3.7 A. The diffraction patterns suggest that the cro-DNA complexes are arranged in an open hexagonal network with the DNA fragments stacked end-to-end. The DNA is in the B-form but appears to be bent or curved into an approximate superhelix.
