X-ray diffraction studies on crystalline complexes of the gene 5 DNA-unwinding protein with deoxyoligonucleotides.

Complexes of the gene 5 protein with a variety of oligodeoxynucleotides, ranging in length from two to eight and having several different sequences, have been formed and crystallized for x-ray diffraction analysis. The crystallographic parameters of four different unit cells, all of which are based on hexagonal packing arrangements, indicate that the fundamental unit of the complex is composed of 12 gene 5 monomers.
