In this context, we introduce a strategy employing a cyclic disulfide-substituted acylating agent to randomly acylate the 2′-OH group on the gRNA strand. The CRISPR-Cas systems demonstrate off–on transformation activity driven by redox-triggered disulfide cleavage and undergo intramolecular cyclization, which releases the functionalized gRNA.
