tRNA-splicing ligase, RtcB (IPR001233)

Short name: RtcB

Overlapping homologous superfamilies

Family relationships


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 [PMID: 21224389].
