 RtcB
PFAM accession number:PF01139
Interpro abstract (IPR001233):

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) ].

GO process:RNA processing (GO:0006396)
GO function:RNA ligase activity (GO:0008452)
