The host-guest recognition system is incorporated into the core region of the 10-23 DNAzyme for precise regulation of its functionality. Biochemical experiments demonstrate reversible and orthogonal control of the DNAzyme function using cucurbit(7)uril and its competitive guests. Furthermore, cellular experiments indicate the gene expression can be effectively manipulated through this ligand-controllable DNAzyme.
