-. M410. T4 Polynucleotide Kinase. 2. -. C131.
T4 Polynucleotide Kinase catalyzes the transfer and exchange of P from the γ position of ATP to the 5´ -hydroxyl terminus of double- and single-stranded DNA and RNA, as well as nucleoside 3´-monophosphates (1-5). This modified version exhibits full kinase activity with no 3´ phosphatase activity (6,7). Polynucleotide kinase/phosphatase (PNKP) processes strand-break termini to render them chemically compatible for the subsequent action of DNA polymerases and ligases. Here, we demonstrate that functionally active full-length PNKP is present in mitochondria as well as nuclei.

PNK from bacteriophage T4 is widely used in molecular biology for 5′ phosphorylation of DNA and RNA for the purpose of labeling and ligation, as well as the removal of 3′phosphoryl groups from various nucleotide and nucleic acid substrates for labeling … with T4 Polynucleotide Kinase 1. Prepare the following reaction mixture: Linear ds DNA or Oligonucleotide 1-20 pmol of 5'-termini or 10-50 pmol 10x reaction buffer A for T4 Polynucleotide Kinase 2 µL ATP, 10 mM* 2 µL T4 Polynucleotide Kinase 1 µL … T4 polynucleotide kinase (Pnk), in addition to being an invaluable research tool, exemplifies a family of bifunctional enzymes with 5'-kinase and 3'-phosphatase activities that play key roles in T4 polynucleotide kinase catalyzes the transfer and exchange of phosphate groups from the γ-position of ATP to the 5’–hydroxyl terminus of nucleic acids (double and single-stranded DNA and RNA). It can be used for the phosphorylation of DNA fragments or PCR primers.

In response to ionizing radiation or oxidative damage, the protein encoded by this locus catalyzes 5' phosphorylation and 3' dephosphorylation of nucleic acids. 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..

Polynucleotide Kinase also catalyzes the removal of 3´-phosphoryl groups from 3´-phosphoryl polynucleotides, deoxynucleoside 3´-monophosphates and deoxynucleoside 3´-diphosphates (1). Product Source A E. coli strain that carries the cloned T4 Polynucleotide Kinase gene. 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).

T4 Polynucleotide Kinase (T4 PNK) Applications. Dephosphorylation of DNA, RNA and oligonucleotides. Dephosphorylation of vector DNA. Dephosphorylation of proteins. Phosphorylation of PCR products.
This modified version exhibits full kinase activity with no 3´ … T4 Polynucleotide Kinase catalyzes the transfer and exchange of P i from the γ position of ATP to the 5´ -hydroxyl terminus of double- and single-stranded DNA and RNA, as well as nucleoside 3´-monophosphates (1-5). This modified version exhibits full kinase activity with no 3´ … A polynucleotide kinase from the thermophilic bacte-riophage RM378 that infects the thermophilic eubacte-rium Rhodothermus marinus was identified, expressed, and purified. This polynucleotide kinase was demon-strated to have a 5-kinase domain as well as a 3 -phos-phohydrolase domain. 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.
