Thermo Scientific™ T4 Polynucleotide Kinase (T4 PNK) catalyzes the transfer of the gamma-phosphate from ATP to the 5'-OH group of single- and double-stranded DNAs and RNAs, oligonucleotides, or nucleoside 3'-monophosphates (forward reaction). The reaction is reversible. Polynucleotide Kinase also catalyzes the removal of 3´-phosphoryl groups from 3´-phosphoryl polynucleotides, deoxynucleoside 3´-monophosphates and deoxynucleoside 3´-diphosphates (1). Search results for Polynucleotide Kinase at Sigma-Aldrich. Summary: This locus represents a gene involved in DNA repair.
Determination of nucleotide kinase activity is valuable due to its importance in regulating nucleic acid metabolism. In this work, a novel and simple colorimetric method for discriminative detection of T4 polynucleotide kinase (PNK) through a MnO2 nanosheet-3,3′,5,5′-tetramethylbenzidine (TMB) colorimetric s The PNKP gene provides instructions for making the polynucleotide kinase-phosphatase (PNKP) enzyme. This enzyme is critical for repairing broken strands of DNA molecules. It can help fix damage that affects one DNA strand (single-strand breaks) or both strands (double-strand breaks).

It also synthesizes long, highly heteropolymeric tails in vivo. T4 Polynucleotide Kinase catalyzes the transfer of the γ-phosphate from ATP to the 5´-terminus of polynucleotides or to mononucleotides bearing a 5´-hydroxyl group. The enzyme may be used to phosphorylate RNA, DNA and synthetic oligonucleotides prior to subsequent manipulations such as ligation and cloning.

In the presence of ADP, T4 Polynucleotide Kinase exhibits 5'-phosphatase Polynucleotide kinase is a T7 bacteriophage (or T4 bacteriophage) enzyme that catalyzes the transfer of a gamma- phosphate from ATP to the free hydroxyl end of the 5' DNA or RNA. The resulting product could be used to end-label DNA or RNA, or in a ligation reactions.. 2002-09-01 · T4 polynucleotide kinase (PNK) is one of the most frequently used enzymes in molecular biology. In vivo, T4 PNK employs 5′-kinase and 3′-phosphatase activities to repair the damaged termini of nicked tRNA molecules during a host-cell suicide response. Polynucleotide kinase catalyzes the transfer of the terminal phosphate group of ATP to the 5′-hydroxyl terminus of DNA or RNA. It also can catalyze the exchange of 5′-terminal phosphate groups. In addition, the enzyme has a 3′-phosphatase activity (only at low pH). Polynucleotide kinase (PNK) is an enzyme that catalyzes the reversible phosphorylation of nucleoside monophosphates, ss and ds nucleic acids.
