Description: T4 PNK catalyzes the transfer of the terminal phosphate of ATP to 5'-hydroxyl termini of polynucleotides such as DNA and RNA, oligonucleotides and 3'-mononucleotides. In the presence of ADP, it will also catalyze the exchange of 5'-terminal phosphate groups and ATP. This enzyme also possesses a 3'-phosphatase and 2', 3' cyclic phosphodiesterase activity.
