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_00044}.
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         Rule:MF_00044};
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00044}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00044}.
CC   -!- SIMILARITY: Belongs to the class-II aminoacyl-tRNA synthetase family.
CC       Type 1 subfamily. {ECO:0000255|HAMAP-Rule:MF_00044}.
