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 Rule:MF_03125}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_03125}.
CC -!- SIMILARITY: Belongs to the adenylosuccinate synthetase family.
CC {ECO:0000256|HAMAP-Rule:MF_03125, ECO:0000256|RuleBase:RU000520}.
