T4 RNA ligase, the product of the phage gene 63, is purified from phage-infected cells. It catalyzes the ATP-dependent covalent joining of single-stranded 5'-phosphoryl termini of DNA or RNA to single-stranded 3'-hydroxyl termini of DNA or RNA. This unit describes specific reaction conditions as well as applications such as radioactive labeling of 3' termini of RNA, circularizing deoxy- and ribo-oligonucleotides, ligating oligomers for oligonucleotide synthesis, and stimulating the blunt-end ligation activity of T4 DNA ligase.
