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). 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).

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. T4 polynucleotide kinase catalyzes the transfer of the terminal phosphate group of ATP to the 5′-hydroxyl terminus of DNA or RNA. It also can catalyze the exchange of 5′-terminal phosphate groups.

Polynucleotide kinase

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 breaks).

Vi är stolta över att lista förkortningen av PNK i den största databasen av förkortningar och akronymer. Följande bild visar en av definitionerna för PNK på engelska: Polynucleotide Kinase. Pnkp is composed of three catalytic modules: an N-terminal polynucleotide 5'-kinase, a central 2',3' phosphatase, and a C-terminal ligase. Here we report the crystal structure of the kinase domain of Clostridium thermocellum Pnkp bound to ATP•Mg²⁺ (substrate complex) and ADP•Mg²⁺ (product complex). 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.

While the mammalian enzyme prefers recessed and internal 5′-hydroxyl groups within double stranded substrates, the bacterial enzyme strongly prefers single stranded 5′-hydroxyl ends. 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 RNA and DNA repair.
