This domain is found at the C-terminal end of T4 RNA ligase 1 (Rnl1) from Bacteriophage T4 and similar proteins from tailed bacteriophages. Rnl1 is involved in countering a host defense mechanism by repairing tRNA. The C-terminal domain shows an all alpha-helical fold and has a charge distribution and architecture for helix-nucleic acid groove interaction compatible with tRNA binding. It confers specificity for the repair of tRNAs with breaks in the anticodon loop [1,2].	Domain
