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:0000255|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         Rule:MF_00011};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00011};
CC       Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_00011};
CC   -!- PATHWAY: Purine metabolism; AMP biosynthesis via de novo pathway; AMP
CC       from IMP: step 1/2. {ECO:0000255|HAMAP-Rule:MF_00011}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00011}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00011}.
CC   -!- SIMILARITY: Belongs to the adenylosuccinate synthetase family.
CC       {ECO:0000255|HAMAP-Rule:MF_00011}.
