Purified from a strain of?E.coli?that expresses the recombinant T4 Polynucleotide Kinase gene.
Description :
T4 Polynucleotide Kinase (PNK) catalyzes the transfer and exchange of the terminal gamma position phosphate of ATP to the 5′-hydroxyl terminus of double-and single-stranded DNA, RNA and nucleoside 3′-monophosphate molecules. T4 PNK also exhibits 3′-phosphatase and 2′, 3′ cyclicphosphodiesterase activities.

pseT; polynucleotide kinase; NP_049834.1; 5"-hydroxyl kinase, a 3"-phosphatase and a 2",3"-cyclic phosphodiesterase; catalyzes the transfer of the terminal phosphate of ATP to the 5"-hydroxyl termini of ribo- and deoxyribonucleotides; in the presence of ADP the enzyme also catalyzes the exchange of the 5" terminal phosphate from phosphorylated DNA to ADP; these activities modify the ends of nicked tRNA generated by a bacterial response to infection and facilitate repair by T4 RNA ligase
