case <OC:Apicomplexa> or <OC:Leishmania> or <OC:Trypanosoma>
FUNCTIONPlays an important role in the salvage pathway for purine nucleotide biosynthesis. Catalyzes the first commited step in the biosynthesis of AMP from IMP.
else
FUNCTIONPlays an important role in the de novo pathway and in the salvage pathway of purine nucleotide biosynthesis. Catalyzes the first commited step in the biosynthesis of AMP from IMP.
end case
CATALYTIC ACTIVITY Reaction=IMP + L-aspartate + GTP = N(6)-(1,2-dicarboxyethyl)-AMP + GDP + phosphate + 2 H(+); Xref=Rhea:RHEA:15753, ChEBI:CHEBI:15378, ChEBI:CHEBI:29991, ChEBI:CHEBI:37565, ChEBI:CHEBI:43474, ChEBI:CHEBI:57567, ChEBI:CHEBI:58053, ChEBI:CHEBI:58189; EC=6.3.4.4;
COFACTOR Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Note=Binds 1 Mg(2+) ion per subunit.;
PATHWAYPurine metabolism; AMP biosynthesis via de novo pathway; AMP from IMP: step 1/2.
SUBUNITHomodimer.
case <OG:Organellar chromatophore>
SUBCELLULAR LOCATIONPlastid, organellar chromatophore.
else case <OC:Viridiplantae>
SUBCELLULAR LOCATIONPlastid, chloroplast.
else
SUBCELLULAR LOCATIONCytoplasm.
end case
case <OC:Apicomplexa> or <OC:Leishmania> or <OC:Trypanosoma>
MISCELLANEOUSParasitic protozoa lack the de novo purine biosynthesis pathway and rely exclusively on the salvage pathway for their purine nucleotide requirements.
end case
case <OC:Viridiplantae> and not <AnyFeature:TransitC>
MISCELLANEOUSThis protein may be expected to contain an N-terminal transit peptide but none has been predicted.
end case
SIMILARITYBelongs to the adenylosuccinate synthetase family.
