DNA structure influences sequence specific cleavage by bleomycin.

We have examined the cleavage of several synthetic DNA sequences by iron(II)-bleomycin. We find that, although bleomycin cuts mixed sequence DNAs with a preference for GC = GT > GA >> GG, it efficiently cleaves regions of (AT)n cutting exclusively at ApT, not TpA. Isolated ApT steps show ve...
