CC -!- FUNCTION: An aminoacyl-tRNA editing enzyme that deacylates CC mischarged D-aminoacyl-tRNAs. Also deacylates mischarged glycyl- CC tRNA(Ala), protecting cells against glycine mischarging by AlaRS. CC Acts via tRNA-based rather than protein-based catalysis; rejects CC L-amino acids rather than detecting D-amino acids in the active CC site. By recycling D-aminoacyl-tRNA to D-amino acids and free tRNA CC molecules, this enzyme counteracts the toxicity associated with CC the formation of D-aminoacyl-tRNA entities in vivo and helps CC enforce protein L-homochirality. {ECO:0000255|HAMAP- CC Rule:MF_00518}. CC -!- CATALYTIC ACTIVITY: CC Reaction=glycyl-tRNA(Ala) + H2O = glycine + H(+) + tRNA(Ala); CC Xref=Rhea:RHEA:53744, Rhea:RHEA-COMP:9657, Rhea:RHEA-COMP:13640, CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:57305, CC ChEBI:CHEBI:78442, ChEBI:CHEBI:78522; EC=3.1.1.96; CC Evidence={ECO:0000255|HAMAP-Rule:MF_00518}; CC -!- CATALYTIC ACTIVITY: CC Reaction=a D-aminoacyl-tRNA + H2O = a D-amino acid + H(+) + tRNA; CC Xref=Rhea:RHEA:13953, Rhea:RHEA-COMP:10123, Rhea:RHEA- CC COMP:10124, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, CC ChEBI:CHEBI:59871, ChEBI:CHEBI:78442, ChEBI:CHEBI:79333; CC EC=3.1.1.96; Evidence={ECO:0000255|HAMAP-Rule:MF_00518}; CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00518}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00518}. CC -!- DOMAIN: A Gly-cisPro motif from one monomer fits into the active CC site of the other monomer to allow specific chiral rejection of L- CC amino acids. {ECO:0000255|HAMAP-Rule:MF_00518}. CC -!- SIMILARITY: Belongs to the DTD family. {ECO:0000255|HAMAP- CC Rule:MF_00518}.
