Nuclease enzymes are hydrolases that break down DNA and RNA by cleaving the phosphodiester bonds linking nucleotides. They achieve this through hydrolysis, often requiring cofactors like magnesium or zinc to stabilize reaction intermediates.
Reported Benefits (Provisional)
Origin & History
Nuclease enzymes (EC 3.1.x.x) are ubiquitous hydrolases found in all living organisms, including humans, bacteria, and viruses, that catalyze the hydrolysis of phosphodiester bonds within nucleic acids (DNA and RNA). These enzymes are essential for maintaining genomic integrity, regulating gene expression, and facilitating nucleic acid metabolism. Their diverse functions range from DNA repair and replication to antiviral defense and programmed cell death.
Research Narrative (Provisional)
Nuclease enzymes have been extensively studied through biochemical, genetic, and clinical research, elucidating their fundamental roles in DNA repair, replication, and RNA metabolism. Peer-reviewed studies, including clinical trials for specific therapeutic applications like dornase alfa in cystic fibrosis, confirm their utility in maintaining genomic stability and their transformative potential in gene editing technologies.

Nutritional Profile
- Endonucleases: Cleave phosphodiester bonds within a polynucleotide chain (e.g., DNase I, RNase A) - Exonucleases: Cleave phosphodiester bonds from the ends of a polynucleotide chain - Substrate specificity: DNA (DNases) or RNA (RNases)
Reported Mechanism (Provisional)
Nuclease enzymes, classified as hydrolases, cleave phosphodiester bonds in DNA and RNA through hydrolysis, utilizing water molecules. They identify and bind to specific nucleotide sequences via their active sites, facilitating the removal of nucleotides. Many nucleases require essential cofactors such as magnesium, calcium, or zinc to stabilize the intermediate products during this bond-breaking process.
Clinical Narrative (Provisional)
Clinical research, including peer-reviewed studies and clinical trials, has investigated therapeutic applications of nuclease enzymes, such as dornase alfa in cystic fibrosis. While specific sample sizes and detailed outcomes beyond its use as a mucolytic agent are not universally available, studies generally focus on its ability to degrade extracellular DNA in sputum. These investigations highlight the targeted enzymatic activity for specific disease management, supporting its role in improving respiratory function in CF patients.
