Plays a key role in the repair of DNA damage, functioning as part of both the non-homologous end-joining (NHEJ) and base excision repair (BER) pathways. Through its two catalytic activities, PNK ensures that DNA termini are compatible with extension and ligation by either removing 3'-phosphates from, or by phosphorylating 5'-hydroxyl groups on, the ribose sugar of the DNA backbone.

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.

T4 polynucleotide kinase (PNK) is one of the most frequently used enzymes in molecular biology. In vivo, T4 Figures. 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. 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..

Product Source T4 Polynucleotide Kinase E.C. 2.7.1.78 Description T4 Polynucleotide Kinase (polynucleotide 5′-hydroxyl-kinase or ATP:5′-dephospho-polynucleotide 5′ phosphatase) T4 Polynucleotide Kinase (T4 PNK; Cat.# M4101, M4103) is a tetramer composed of identical subunits and has multiple activities. The 5′-kinase activity of T4 PNK catalyzes polynucleotide kinase PNK An enzyme that facilitates the transfer of a phosphate group from adenosine triphosphate to the 5′ terminus of a nucleic acid (RNA or DNA). 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. Mammalian polynucleotide kinase and its bacterial ortholog, T4 polynucleotide kinase, display strikingly different kinase substrate preferences.
