In the type I CISPR/Cas system the crRNA guides the surveillance complex Cascade ABCDE to complementary DNA sequence. The DNA is unwound, generating the so-called R-loop. The Cas3 helicase-nuclease protein attaches to this R-loop and unidirectionally degrades the DNA. Hereby, the large Cas3/Cascade complex pulls the substrate DNA towards itself, introducing single strand breaks.
