Description_x000D_ General description_x000D_ Nuclease P1 (Nuclease 5′-Nucleotidehydrolase, 3′- Phosphohydrolase, EC 3.1.30.1), also known as deoxyribonuclease P1 or endonuclease P1, is a zinc dependent endonuclease. It is isolated from Penicillium citrinum._x000D_ Immunogen_x000D_ Nuclease P1 from Penicillium citrinum_x000D_ Application_x000D_ Anti-Nuclease P1 antibody produced in rabbit has been used in immunoblotting._x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide._x000D_ Biochem/physiol Actions_x000D_ Nuclease P1 catalyzes the hydrolysis of 3′-5′ phosphodiester bonds in RNA and single-stranded DNA and 3′-phosphomonoester bonds in mono- and oligonucleotides terminated by a 3′-phosphate group without apparent bases specificity. The enzyme is used as a component of nuclease cocktail to generate single-stranded oligodeoxynucleotide (ODNs) samples for mass spectroscopy research for characterization of oligodeoxyribonucleotides. Nuclease P1 has also been widely used in the food industry to enhance or create flavor.
