Structure of fungal tRNA ligase Trl1 with RNA reveals conserved substrate-binding principles

{{output}}
RNA ligases play a vital role in RNA processing and maturation, including tRNA splicing, RNA repair and the unfolded protein response (UPR). In fungi and plants, the tripartite tRNA ligase Trl1 catalyzes the joining of TSEN-cleaved pre-tRNA exon halves. Trl1 a... ...
