    GO ID   Ontology GO Term Definition
    737   DNA Catabolic Process Endonucleolytic  The Chemical Reactions and Pathways Resulting in the Breakdown of DNA Involving the Hydrolysis of Internal 3' 5' Phosphodiester Bonds in One or Two Strands of Deoxyribonucleotides. 
    9307   DNA Restriction Modification System  A Defense Process Found in Many Bacteria and Archaea That Protects the Organism From Invading Foreign DNA by Cleaving It with a Restriction Endonuclease. the Organism's Own DNA Is Protected by Methylation of a Specific Nucleotide Which Occurs Immediately Following Replication in the Same Target Site As the Restriction Enzyme. 
    90305   Nucleic Acid Phosphodiester Bond Hydrolysis  The Nucleic Acid Metabolic Process in Which the Phosphodiester Bonds Between Nucleotides Are Cleaved by Hydrolysis. 
    3677   DNA Binding  Any Molecular Function by Which a Gene Product Interacts Selectively and Non Covalently with DNA (deoxyribonucleic Acid). 
    4518   Nuclease Activity  Catalysis of the Hydrolysis of Ester Linkages Within Nucleic Acids. 
    4519   Endonuclease Activity  Catalysis of the Hydrolysis of Ester Linkages Within Nucleic Acids by Creating Internal Breaks. 
    9036   Type Ii Site Specific Deoxyribonuclease Activity  Catalysis of the Endonucleolytic Cleavage of DNA to Give Specific Double Stranded Fragments with Terminal 5' Phosphates and 3' Hydroxyls. Cleavage Is Dependent On the Presence in the DNA of a Specific Recognition Site; Cleavage Occurs At or Very Near This Recognition Site. 
    16787   Hydrolase Activity  Catalysis of the Hydrolysis of Various Bonds E.g. C O C N C C Phosphoric Anhydride Bonds Etc. Hydrolase Is the Systematic Name For Any Enzyme of EC Class 3. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion.
