T4 RNA Ligase 2

T4 RNA Ligase 2, also known as T4 Rnl2 (gp24.1), has both intermolecular and intramolecular RNA strand joining activity. T4 RNA Ligase 2 is more active for joining nicks on double stranded RNA than on joining the ends of single stranded RNA. The enzyme requires an adjacent 5´ phosphate and 3´ OH for ligation. The enzyme can also ligate the 3´ OH of RNA to the 5´ phosphate of DNA in a double stranded structure. The non-ligated strand of the duplex can be either RNA or DNA. T4 RNA ligase 2 requires ATP for activity unless the substrate is preadenylated on the 5ʹ end.   Activity: 10,000 U/mL (>40,000 U/mg).
