Nuclease P1 (Nuclease 5'-Nucleotidehydrolase, 3'-Phosphohydrolase, NP1)

Nuclease P1 (Nuclease 5'-Nucleotidehydrolase, 3'-Phosphohydrolase) from Penicillium citrinum, a zinc dependent glyco-enzyme consisting of 270 amino acid residues, hydrolyzes both 3'-5'-phosphodiester bonds in RNA and heat denatured DNA and 3'-phosphomonoester bonds in mono- and oligonucleotides terminated by 3'-phosphate without base specificity. Nuclease P1 is capable of hydrolyzing single stranded DNA and RNA completely to the level of mononucleoside 5пїЅ-monophosphates. The enzyme does not attack double-stranded nucleic acids, especially in the presence of more than 400mM of sodium chloride at pH 6.0.\n\nActivity:\n> 300U/mg protein using RNA substrate\n\nUnit Definition:\nOne unit of nuclease activity is defined as the amount of enzyme that produces 1umole of acid soluble nucleotides from RNA based on E = 10,600 for RNA hydrolysates per minute at 37 degrees C, pH 5.3. One unit of the enzyme liberates 1umole of orthophosphate from 3пїЅ-AMP per minute at 37 degrees C, pH 7.2\n\nOptimum Temperature: ~70 degrees C [< 60 degrees C for long incubations]\n\nStable pH: 5.0-8.0 \n\nReconstitution:\nFor maximum recovery of product, briefly centrifuge the original vial prior to opening. This will dislodge any enzyme that has adhered to the side or in the cap due to shipping. Reconstitute with sterile ddH2O. Allow the nuclease to rest on ice for ~10-15 minutes. Vortex gently to ensure there is uniform suspension (Nuclease tends to become layered towards the bottom of the vial). Just before addition to the reaction mixture, gently vortex the suspension. \n\nStorage and Stability:\nLyophilized powder may be stored at -20 degrees C. Stable for 12 months. Reconstituted product should be aliquoted and stored at -20 degrees C. Reconstituted product is stable for 2-3 weeks at 4 degrees C and 3-6 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
