Cas protein mechanism is as follows: (A) Type I system depends on Cas3 protein, which recognizes new viral infection and counters it, (B) Type II system depends on Cas9 proteins and tracrRNA for the biogenesis of crRNA, and (C) Type III system depends on either Cas6 or Cas10 in which Csm targets DNA while Cmr targets viral RNA.
