case <OC:Apicomplexa> or <OC:Leishmania> or <OC:Trypanosoma> | |
FUNCTION | Plays an important role in the salvage pathway for purine nucleotide biosynthesis. Catalyzes the first commited step in the biosynthesis of AMP from IMP. |
else | |
FUNCTION | Plays 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=GTP + IMP + L-aspartate = GDP + 2 H(+) + N(6)-(1,2- dicarboxyethyl)-AMP + phosphate; 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.; |
PATHWAY | Purine metabolism; AMP biosynthesis via de novo pathway; AMP from IMP: step 1/2. |
SUBUNIT | Homodimer. |
case <OG:Organellar chromatophore> | |
SUBCELLULAR LOCATION | Plastid, organellar chromatophore. |
else case <OC:Viridiplantae> | |
SUBCELLULAR LOCATION | Plastid, chloroplast. |
else | |
SUBCELLULAR LOCATION | Cytoplasm. |
end case | |
case <OC:Apicomplexa> or <OC:Leishmania> or <OC:Trypanosoma> | |
MISCELLANEOUS | Parasitic 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> | |
MISCELLANEOUS | This protein may be expected to contain an N-terminal transit peptide but none has been predicted. |
end case | |
SIMILARITY | Belongs to the adenylosuccinate synthetase family. |
