生化/生理作用
Nuclease S7 is an endonuclease that mainly cleaves single-stranded substrates. It also cleaves double-stranded DNA or RNA. It cleaves the 5′-phosphodiester bonds of RNA and DNA to yield 3′-mononucleotides and oligonucleotides. Activity of the enzyme is dependent on Ca2+ and can be completely inactivated by the addition of EDTA. Nuclease S7 cleavage is highly specific to AT rich region than GC on the DNA.
