WebWhile the common 'wild type' form of the Cas9 protein snips both strands in DNA, there are also 'mutant' forms that serve as a nickase -- an enzyme that only nicks one strand. Another useful variant is 'dead Cas9' or dCas9 , in which the HNH and RuvC domains have been mutated to deactivate its cutting ability, allowing the enzyme to target -- but not damage - … WebJun 22, 2024 · The dCas9, also known as endonuclease deficient Cas9, is a mutant form of Cas9, whose endonuclease activity is removed by mutating the endonuclease domains.
