| - | T4 RNA ligase 2 (Rnl2) exemplifies an RNA ligase family that includes the RNA editing ligases (RELs) of Trypanosoma and Leishmania. The Rnl2/REL enzymes are defined by essential signature residues and a unique C-terminal domain, which we show is essential for sealing of 3'-OH and 5'-PO4 RNA ends by Rnl2, but not for ligase adenylation or phosphodiester bond formation at a preadenylated AppRNA end. The N-terminal segment Rnl2(1-249) of the 334 aa Rnl2 protein comprises an autonomous adenylyltransferase/AppRNA ligase domain. We report the 1.9 A crystal structure of the ligase domain with AMP bound at the active site, which reveals a shared fold, catalytic mechanism, and evolutionary history for RNA ligases, DNA ligases, and mRNA capping enzymes. | ||
