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 = glycine + H(+) + tRNA(Ala);

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 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}.
