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. 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 (PNK) is an enzyme that catalyzes the reversible phosphorylation of nucleoside monophosphates, ss and ds nucleic acids. 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 Main Text T4 polynucleotide kinase (PNK) is one of the most frequently used enzymes in molecular biology.

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. 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 purposes. Polynucleotide kinase/phosphatase (PNKP) processes strand-break termini to render them chemically compatible for the subsequent action of DNA polymerases and ligases.

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.

The reaction is reversible. In the presence of ADP T4 Polynucleotide Kinase exhibits Description 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. 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 The PNKP gene provides instructions for making the polynucleotide kinase-phosphatase (PNKP) enzyme.
