Chain A,B   (T2P2_PROHU | P23657)
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.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0004518    nuclease activity    Catalysis of the hydrolysis of ester linkages within nucleic acids.
biological process
    GO:0009307    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.
    GO:0090305    nucleic acid phosphodiester bond hydrolysis    The nucleic acid metabolic process in which the phosphodiester bonds between nucleotides are cleaved by hydrolysis.
