The study found an unexpected difference in the DNAzyme activity between in vitro assays and in mitochondria, with molecular dynamic simulations illustrating how the interaction of G-quadruplex with hemin could modulate the DNAzyme activity. These results may aid in better understanding the catalytic mechanism of DNAzymes and in designing stable and active DNAzymes for intracellular catalysis.
The DNAzyme activity of G-quadruplex/hemin in mitochondria has not been characterized. Herein, we report an unexpected difference in the DNAzyme activity between in vitro assays and in mitochondria. Molecular dynamic simulations illustrate how the interaction of the G-quadruplex with hemin may modulate the DNAzyme activity. These results might facilitate a better understanding of the catalytic mechanism of the DNAzyme and help the rational design of stable and active DNAzymes suitable for intracellular catalysis.
