MeSH Heading: Deoxyribonucleases, Type I Site-Specific
Tree Number(s): D08.811.150.280.250; D08.811.277.352.335.350.300.250; D08.811.277.352.355.325.300.250
Unique ID: D015253
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D015253
Scope Note: Enzyme systems containing three different subunits and requiring ATP, S-adenosylmethionine, and magnesium for endonucleolytic activity to give random double-stranded fragments with terminal 5'-phosphates. They function also as DNA-dependent ATPases and modification methylases, catalyzing the reactions of EC 2.1.1.72 and EC 2.1.1.73 with similar site-specificity. The systems recognize specific short DNA sequences and cleave at sites remote from the recognition sequence. Enzymes from different microorganisms with the same specificity are called isoschizomers. EC 3.1.21.3.
