deoxyribonucleases, type III site-specific (medicine)


deoxyribonucleases, type III site-specific
<enzyme> Enzyme systems composed of two subunits and requiring ATP and magnesium for endonucleolytic activity; they do not function as atpases. They exist as complexes with modification methylases of similar specificity.

The systems recognise specific short DNA sequences and cleave a short distance, about 24 to 27 bases, away from the recognition sequence to give specific double-stranded fragments with terminal 5'-phosphates. Enzymes from different microorganisms with the same specificity are called isoschizomers.

Registry number: EC 3.1.21.5
