RNA ligase

spinqualitylabelsall models Se-Met RNA ligase (PDB code 1vgj) Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image   Print3D RNA ligase (LigR) is an enzyme which ligates two ribonucleotide chains using ATP and producing AMP, diphosphate and the ligated ribonucleotide chain. RNA ligase RtcB joins 2',3'-cyclic phosphate and 5'-OH ends. See more details in T4 RNA ligase 2 (Rnl2) and Ligases.
