Genome-wide mapping of helicase-generated ssDNA reveals Hrq1 activity at RNA polymerase III-transcribed genes
DNA helicases preserve genome stability by unwinding DNA during replication, repair, recombination, and transcription, yet their sites of action in vivo remain difficult to define. Here, we describe a sequencing-based strategy to map helicase activity genome-wide by coupling helicases to the single-stranded DNA-specific activation-induced cytidine deaminase (AID). Deamination of cytosines exposed…
