Introduction

Pfam

This family of RNA ligases ( EC:6.5.1.3) join 2',3'-cyclic phosphate and 5'-OH ends. They catalyse the splicing of tRNA and may also participate in tRNA repair and recovery from stress-induced RNA damage [1-3].

RctB is a RNA ligase that mediates the joining of broken tRNA-like stem-loop structures in case of tRNA damage. It probably participates to tRNA restriction-repair by ligating broken tRNA-like stem-loop structures with 2',3'-cyclic phosphate and 5'-OH ends to form a splice junction with a 2'-OH, 3',5'-phosphodiester [PUBMED:21224389].
