CC -!- FUNCTION: Aspartyl-tRNA synthetase with relaxed tRNA specificity since
CC it is able to aspartylate not only its cognate tRNA(Asp) but also
CC tRNA(Asn). Reaction proceeds in two steps: L-aspartate is first
CC activated by ATP to form Asp-AMP and then transferred to the acceptor
CC end of tRNA(Asp/Asn). {ECO:0000255|HAMAP-Rule:MF_02075}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-aspartate + tRNA(Asx) = AMP + diphosphate + L-
CC aspartyl-tRNA(Asx); Xref=Rhea:RHEA:18349, Rhea:RHEA-COMP:9710,
CC Rhea:RHEA-COMP:9711, ChEBI:CHEBI:29991, ChEBI:CHEBI:30616,

CC ChEBI:CHEBI:456215; EC=6.1.1.23; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_02075};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_02075};
CC Note=Binds 3 Mg(2+) cations per subunit. The strongest magnesium site
CC (Mg1) is bound to the beta- and gamma-phosphates of ATP and four water
CC molecules complete its coordination sphere. {ECO:0000255|HAMAP-
CC Rule:MF_02075};
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_02075}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_02075}.
CC -!- SIMILARITY: Belongs to the class-II aminoacyl-tRNA synthetase family.
CC Type 2 subfamily. {ECO:0000255|HAMAP-Rule:MF_02075}.
