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. 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 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).

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).

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..

5′-ends of purified pooled amplicons (1 μg) were phosphorylated using T4 Polynucleotide Kinase (Promega) following the manufacturer's recommendation.

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. with T4 Polynucleotide Kinase 1.

Mammalian polynucleotide kinase (PNK) is a key component of both the base excision repair (BER) and nonhomologous end-joining (NHEJ) DNA repair pathways. PNK acts as a 5'-kinase/3'-phosphatase to create 5'-phosphate/3'-hydroxyl termini, which are a necessary prerequisite for ligation during repair.

5′-Polynucleotide kinase such as T4 polynucleotide kinase (T4 PNK) may catalyze the phosphorylation of 5′-hydroxyl termini in nucleic acids, playing a crucial role in DNA replication, DNA recombination, and DNA damage repair. Here, we demonstrate for the first time single-molecule detection of PNK based on phosphorylation-directed recovery of fluorescence quenched by Au nanoparticle (AuNP Polynucleotide Kinase also catalyzes the removal of 3´-phosphoryl groups from 3´-phosphoryl polynucleotides, deoxynucleoside 3´-monophosphates and deoxynucleoside 3´-diphosphates (1).

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 DNA ends are processed by a series of proteins, including poly(ADP-ribose) polymerase 1 (PARP1), XRCC1, polynucleotide kinase/phosphatase (PNKP), polynucleotide kinase = polynucléotide kinase.
