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 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 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. The kinetics of T4 polynucleotide kinase has been investigated at pH 8.0 and 37 degrees. Double reciprocal plots of initial rates vs. substrate concentrations as well as product inhibition studies have indicated that the enzyme reacts according to the ordered sequential mechanism shown in eq 2 in th … T4 Polynucleotide Kinase，简称T4 PNK，中文名称T4多聚核苷酸激酶，是一种多聚核苷酸5'羟基激酶，可以催化ATP的γ位磷酸基团向单链或双链DNA、RNA、寡核苷酸或带有3'磷酸基团的单核苷酸的5'羟基转移。 The structure of T4 polynucleotide kinase reveals a tetramer that could process eight ends of four substrates simultaneously.

PNK, Putri Naga  Brukte alkaliske ph er i sexse eskorte jenter gardermoen stand til å minimere enzymaktiviteten av t4-polynucleotide kinase til dephosphorylate  Polynucleotide Kinase also catalyzes the removal of 3´-phosphoryl groups from 3´-phosphoryl polynucleotides, deoxynucleoside 3´-monophosphates and deoxynucleoside 3´-diphosphates (1). Main Text 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. 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 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´ phosphatase activity (6,7). Product Source 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 break Polynucleotide Kinase also catalyzes the removal of 3´-phosphoryl groups from 3´-phosphoryl polynucleotides, deoxynucleoside 3´-monophosphates and deoxynucleoside 3´-diphosphates (1).
