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:0000256|HAMAP-Rule:MF_00518,
CC       ECO:0000256|SAAS:SAAS01081655}.

CC       ECO:0000256|SAAS:SAAS00388074}.
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:0000256|HAMAP-Rule:MF_00518}.
