The Many

<div>The union of transition metal catalysis with native biochemistry presents a powerful opportunity</div><div>to perform abiotic reactions within complex biological systems.(1,2) However, several chemical</div><div>compatibility challenges associated with incorporating reactive metal centers into complex</div><div>biological environments have hindered efforts in this area, despite the many opportunities it may</div><div>present. More challenging than chemical compatibility is biocommunicative transition metal</div><div>catalysis, where the reactivity of the metal species is regulated by native biological stimuli, akin</div><div>to natural biocatalytic processes. Here we report a novel Au(I)-DNAzyme that is activated by short</div><div>nucleic acids in a highly sequence-specific manner and that is compatible with complex biological</div><div>matrices. The active Au(I)-DNAzyme catalyzes the formation of a fluorescent molecule with >10</div><div>turnovers. This functional allostery, resulting in chemocatalytic signal amplification, is competent</div><div>in complex biological settings, including within recombinant E. coli cells, where the catalytic</div><div>activity of the Au(I)-DNAzyme is regulated by transcription of an inducible plasmid. We further</div><div>demonstrate the potential of this transition metal oligonucleotide complex as a highly sensitive and</div><div>selective hybridization probe, permitting the detection of attomolar concentrations (ca. 60</div><div>molecules/µL) of SARS-CoV-2 RNA gene fragments in simulated biological matrices with ≥85%</div><div>accuracy. Notably, this sensitive detection platform avoids expensive and poorly-scalable</div><div>biochemical components (e.g. post-synthetically modified oligonucleotides or enzymes) and</div><div>utilizes small molecule fluorophores, inexpensive Au salts and oligonucleotides composed of</div><div>canonical bases. This discovery highlights promising opportunities to perform abiotic catalysis in</div><div>complex biological settings under transcriptional regulation, as well as a chemocatalytic strategy</div><div>for PCR-free, direct-detection of RNA and DNA.</div><div><br></div>
