The last few years have seen the increasing development of new DNA targeting molecular tools and strategies for precise genome editing. However, opportunities subsist to either improve or expand the current toolbox and further broaden the scope of possible biotechnological applications. Here we report the discovery and the characterization of BurrH, a new modular DNA binding protein from Burkholderia rhizoxinica that is composed of highly polymorphic DNA targeting modules. We also engineered this scaffold to create a new class of designer nucleases that can be used to efficiently induce in vivo targeted mutagenesis and targeted gene insertion at a desired locus.

A key issue when designing and using DNA-targeting nucleases is specificity. Ideally, an optimal DNA-targeting tool has only one recognition site within a genomic sequence. In practice, however, almost all designer nucleases avail...
