Publication Abstract from PubMed

The Z-DNA-binding domain of PKZ from zebrafish (Danio rerio; drZalphaPKZ ) contains the largest beta-wing among known Z-DNA-binding domains. To elucidate the functional implication of the beta-wing, we solved the crystal structure of apo-drZalphaPKZ . Structural comparison with its Z-DNA-bound form revealed a large conformational change within the beta-wing during Z-DNA binding. Biochemical studies of protein mutants revealed that two basic residues in the beta-wing are responsible for Z-DNA recognition as well as fast B-Z transition. Therefore, the extra basic residues in the beta-wing of drZalphaPKZ are necessary for the fast B-Z transition activity.
