NMR Structure(hide GO term definitions)
Chain A   (IPI1_BPT4 | P03718)
molecular function
    GO:0032067    Type IV site-specific deoxyribonuclease activity    Catalysis of the endonucleolytic cleavage of DNA in a site specific manner. Cleavage is dependent on the presence of a specific recognition site in the DNA which must be modified (e.g. methylated, hydroxymethylated, glucosyl-hydroxymethylated).
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.
