    Z-DNA binding proteins (ZBPs) play important roles in RNA editing, innate immune response and viral infection. Structural and biophysical studies show that ZBPs initially form an intermediate complex with B-DNA for B-Z conversion. However, a comprehensive understanding of the mechanism of Z-DNA binding and B-Z transition is still lacking, due to the absence of structural information on the intermediate complex. Here, we report the solution structure of the Zα domain of the ZBP-containing protein kinase from Carassius auratus(caZαPKZ). We quantitatively determined the binding affinity of caZαPKZ for both B-DNA and Z-DNA and characterized its B-Z transition activity, which is modulated by varying the salt concentration. Our results suggest that the intermediate complex formed by caZαPKZ and B-DNA can be used as molecular ruler, to measure the degree to which DNA transitions to the Z isoform.
