molecular function
    GO:0009036    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.
    GO:0004519    endonuclease activity    Catalysis of the hydrolysis of ester linkages within nucleic acids by creating internal breaks.
    GO:0016787    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.
biological process
    GO:0006259    DNA metabolic process    Any cellular metabolic process involving deoxyribonucleic acid. This is one of the two main types of nucleic acid, consisting of a long, unbranched macromolecule formed from one, or more commonly, two, strands of linked deoxyribonucleotides.
    GO:0090305    nucleic acid phosphodiester bond hydrolysis    The nucleic acid metabolic process in which the phosphodiester bonds between nucleotides are cleaved by hydrolysis.
