CC -!- FUNCTION: Catalyzes the attachment of L-aspartate to tRNA(Asp) in a
CC two-step reaction: L-aspartate is first activated by ATP to form Asp-
CC AMP and then transferred to the acceptor end of tRNA(Asp).
CC {ECO:0000255|HAMAP-Rule:MF_00044}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-aspartate + tRNA(Asp) = AMP + diphosphate + L-
CC aspartyl-tRNA(Asp); Xref=Rhea:RHEA:19649, Rhea:RHEA-COMP:9660,

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}.
