Opis ogólny
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.

Zastosowanie
- Nuclease P1 cleave of single stranded DNA or RNA to 5′ mononucleotides
- Nuclease P1 supports DNA damage and modification research
- Nucleic acids base composition and structural analysis can be done by Nuclease P1
- Nuclease P1 has historically been used for the industrial production of 5′-mononucleotides from yeast RNA.
- Removal of nucleic acids through protein purification can be done by Nuclease P1
- Nuclease P1 is a key reagent for the development of methods for studies involving t-RNA dependent amino acid biosynthesis and t-RNA dependent trans-amidation
- Nuclease P1 from Penicillium citrinum has been used in a study to assess crystal structures using ammonium sulphate or polyethylene glycol 4000 as a precipitating agent.
- Nuclease P1 was used in a study to investigate a method for the direct sequence analysis 20-25 nucleotides from the terinini of 5′ or 3′ end group labeled RNA.
- Nuclease P1 is used to improve the sensitivity of a 32P-labeling method for the detection of DNA adducts.
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.
Działania biochem./fizjol.
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.
Cechy i korzyści
Our highly active Nuclease P1 is tested for its 3′- 5′ - Phosphodiesterase Activity and 3′- Nucleotidase Activity and is the most active Nuclease P1 in the market

P1 nuclease, a zinc-dependent single-strand specific endonuclease from Penicillium citrinum, has been crystallized in three different space groups using either ammonium sulphate or polyethylene glycol 4000 as the precipitating agent. The crystals diffract to between 3 A and 2.2 A.

Modified nucleosides on tRNA are critical for decoding processes and protein translation. tRNAs can be modified through 1-methylguanosine (m1G) on position 37; a function mediated by Trm5 homologs. We show that AtTRM5a (At3g56120) is a Trm5 ortholog in Arabidopsis thaliana.
