pfam12623: Hen1_L (This model is not part of the current CDD release)
RNA repair, ligase-Pnkp-associating, region of Hen1
This domain is the N-terminal region of the bacterial Hen1 protein. This protein forms stable hetero-tetramer with Pnkp. The hetero-tetramer was able to repair transfer RNAs cleaved by ribotoxins in vitro. This domain provides the ligase activity of the hetero-tetramer.
