| - | + | [https://www.uniprot.org/uniprot/DTD_PLAF7 DTD_PLAF7] D-aminoacyl-tRNA deacylase, with no observable activity on tRNAs charged with their cognate L-amino acid (PubMed:20007323, PubMed:24302572, PubMed:27224426). Probably acts by rejecting L-amino acids from its binding site rather than specific recognition of D-amino acids (PubMed:27224426). Catalyzes the hydrolysis of D-tyrosyl-tRNA(Tyr), has no activity on correctly charged L-tyrosyl-tRNA(Tyr) (PubMed:20007323, PubMed:24302572, PubMed:27224426). Hydrolyzes correctly charged, achiral, glycyl-tRNA(Gly) (PubMed:27224426). Deacylates mischarged D.melanogaster and E.coli glycyl-tRNA(Ala) (PubMed:28362257). Probably acts via tRNA-based rather than protein-based catalysis (PubMed:24302572, PubMed:27224426). Acts on tRNAs only when the D-amino acid is either attached to the ribose 3'-OH or transferred to the 3'-OH from the 2'-OH through rapid transesterification (PubMed:24302572). Binds a number of other D-amino acids (D-Arg, D-Glu, D-His, D-Lys, D-Ser), suggesting it may also deacylate other mischarged tRNAs (PubMed:20007323).<ref>PMID:20007323</ref> <ref>PMID:24302572</ref> <ref>PMID:27224426</ref> <ref>PMID:28362257</ref> | |
