RT "Complete genome of Caldisphaera lagunensis DSM 15908.";
RL Submitted (MAR-2012) to the EMBL/GenBank/DDBJ databases.
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:0000256|HAMAP-Rule:MF_02075}.
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 Rhea:RHEA-COMP:9678, ChEBI:CHEBI:29991, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:33019, ChEBI:CHEBI:78442, ChEBI:CHEBI:78516,
CC ChEBI:CHEBI:456215; EC=6.1.1.12; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_02075};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|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:0000256|HAMAP-
CC Rule:MF_02075};
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_02075}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_02075}.
CC -!- SIMILARITY: Belongs to the class-II aminoacyl-tRNA synthetase family.
CC Type 2 subfamily. {ECO:0000256|ARBA:ARBA00005312, ECO:0000256|HAMAP-
CC Rule:MF_02075}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_02075}.
