CC   -!- FUNCTION: An aminoacyl-tRNA editing enzyme that deacylates mischarged
CC       D-aminoacyl-tRNAs. Also deacylates mischarged glycyl-tRNA(Ala),
CC       protecting cells against glycine mischarging by AlaRS. Acts via tRNA-
CC       based rather than protein-based catalysis; rejects L-amino acids rather
CC       than detecting D-amino acids in the active site. By recycling D-
CC       aminoacyl-tRNA to D-amino acids and free tRNA molecules, this enzyme
CC       counteracts the toxicity associated with the formation of D-aminoacyl-
CC       tRNA entities in vivo and helps enforce protein L-homochirality.
CC       {ECO:0000255|HAMAP-Rule:MF_00518}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=glycyl-tRNA(Ala) + H2O = tRNA(Ala) + glycine + H(+);

CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00518}.
CC   -!- DOMAIN: A Gly-cisPro motif from one monomer fits into the active site
CC       of the other monomer to allow specific chiral rejection of L-amino
CC       acids. {ECO:0000255|HAMAP-Rule:MF_00518}.
CC   -!- SIMILARITY: Belongs to the DTD family. {ECO:0000255|HAMAP-
CC       Rule:MF_00518}.
