CC -!- FUNCTION: Plays an important role in the de novo pathway and in the
CC salvage pathway of purine nucleotide biosynthesis. Catalyzes the first
CC commited step in the biosynthesis of AMP from IMP. {ECO:0000256|HAMAP-
CC Rule:MF_03125}.
CC -!- FUNCTION: Plays an important role in the de novo pathway of purine
CC nucleotide biosynthesis. {ECO:0000256|RuleBase:RU000520}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=GTP + IMP + L-aspartate = GDP + 2 H(+) + N(6)-(1,2-

CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000256|HAMAP-Rule:MF_03125};
CC -!- PATHWAY: Purine metabolism; AMP biosynthesis via de novo pathway; AMP
CC from IMP: step 1/2. {ECO:0000256|HAMAP-Rule:MF_03125,
CC ECO:0000256|RuleBase:RU000520}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|ARBA:ARBA00011738, ECO:0000256|HAMAP-
CC Rule:MF_03125}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000256|HAMAP-
CC Rule:MF_03125}.
CC -!- SIMILARITY: Belongs to the adenylosuccinate synthetase family.
CC {ECO:0000256|HAMAP-Rule:MF_03125, ECO:0000256|RuleBase:RU000520}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
