The enzyme has an optimal temperature of approximately 70 °C, but for a long incubation, a temperature below 60 °C is more suitable. It is stable in the pH range of 5 - 8.
An enzyme which digests only
single-stranded nucleic acids.
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.
Catalyzes the nonspecific endonucleolytic cleavage of single stranded DNA and RNA to yield nucleoside 5′-phosphates and 5′-phosphooligonucleotides. It does not appreciably degrade double-stranded nucleic acids, especially in the presence of more than 400 mM sodium chloride at pH 6.0.
