CC -!- FUNCTION: Plays an important role in the de novo pathway of purine
CC nucleotide biosynthesis. Catalyzes the first committed step in the
CC biosynthesis of AMP from IMP. {ECO:0000256|HAMAP-Rule:MF_00011}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=GTP + IMP + L-aspartate = GDP + 2 H(+) + N(6)-(1,2-
CC dicarboxyethyl)-AMP + phosphate; Xref=Rhea:RHEA:15753,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:29991, ChEBI:CHEBI:37565,

CC ChEBI:CHEBI:58189; EC=6.3.4.4; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_00011, ECO:0000256|RuleBase:RU000520};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00011};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000256|HAMAP-Rule:MF_00011};
CC -!- PATHWAY: Purine metabolism; AMP biosynthesis via de novo pathway; AMP
CC from IMP: step 1/2. {ECO:0000256|HAMAP-Rule:MF_00011,
CC ECO:0000256|RuleBase:RU000520}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|ARBA:ARBA00011738, ECO:0000256|HAMAP-
CC Rule:MF_00011}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00011}.
CC -!- SIMILARITY: Belongs to the adenylosuccinate synthetase family.
CC {ECO:0000256|HAMAP-Rule:MF_00011, ECO:0000256|RuleBase:RU000520}.
