  • 5' phosphorylation of DNA/RNA for subsequent ligation
  • End labeling DNA or RNA for probes and DNA sequencing
  • Removal of 3' phosphoryl groups

Catalyzes the transfer and exchange of Pi from the γ position of ATP to the 5´ -hydroxyl terminus of polynucleotides (double-and single-stranded DNA and RNA) and nucleoside 3´-monophosphates. 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. It is purified by a modification of the method of Richardson (1).
