설명

일반 설명

Nuclease P1 is one of the most commonly known single-strand specific nucleases in molecular biology; Nuclease P1 is a single stranded specific endoduclease (of ssDNA or ssRNA). Nuclease P1 can also cleave single-stranded regions in double-stranded nucleic acids.
Nuclease P1 from Penicillium citrinum is a zinc-dependent endonuclease that exhibits increased activity in the presence of low concentrations of urea. Nuclease P1 selective activity has found useful applications in studies on nucleic acid structure.
