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:0000256|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 ChEBI:CHEBI:456215; EC=6.1.1.23; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_00044};
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_00044}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00044}.
CC -!- SIMILARITY: Belongs to the class-II aminoacyl-tRNA synthetase family.
CC Type 1 subfamily. {ECO:0000256|ARBA:ARBA00006303, ECO:0000256|HAMAP-
CC Rule:MF_00044}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
