Description
Members of this family include T4 phage proteins with ATP-dependent RNA ligase activity. Host defence to phage may include cleavage and inactivation of specific tRNA molecules; members of this family act to reverse this RNA damage. The enzyme is adenylated, transiently, on a Lys residue in a motif KXDGSL. This family also includes fungal tRNA ligases that have adenylyltransferase activity
[1]. tRNA ligases are enzymes required for the splicing of precursor tRNA molecules containing introns.i
