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.

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. ThermoPhage™ Polynucleotide Kinase is a novel thermoactive kinase catalysing 5’ phosphorylation of DNA at elevated temperatures and is the only available thermostable enzyme of this kind.

In order to demonstrate the cleavage, the substrate strand is radioactively labeled with 32P at the 5' end by T4 polynucleotide kinase.

Table showing properties of alkaline phosphatase and polynucleotide kinase for DNA and RNA dephosphorylation or phosphorylation. 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 T4 Polynucleotide Kinase, supplied by Boehringer Mannheim, used in various techniques.

Sensitive and label-free T4 polynucleotide kinase/phosphatase detection based on poly(thymine)-templated copper nanoparticles coupled with nicking enzyme- T4 polynucleotide kinase exhibits 5'-phosphatase activity and catalyses the exchange of phosphate groups between 5'-P-oligo-polynucleotides and ATP T4 Polynucleotide Kinase.

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 Thermophage™ Polynucleotide Kinase is well suited for various applications including radioactive labelling of nucleic acids (Blondal et al 2005, J Biol Chem 280:5188-94) Available as 500 units and 1000 units (select product above) together with 10x reaction buffers. Involved in countering a host defense mechanism which activates T4-induced anticodon nuclease and shuts off viral translation. The polynucleotide kinase modifies the ends of nicked tRNA generated by the antiviral response of the host bacteria and facilitates repair by T4 RNA ligase (PubMed:2444436). Polynucleotide Phosphorylase (PNPase) is a bifunctional enzyme with a phosphorolytic 3' to 5' exoribonuclease activity and a 3'-terminal oligonucleotide polymerase activity. That is, it dismantles the RNA chain starting at the 3' end and working toward the 5' end. 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.
