Catalytic activity

GTP + IMP + L-aspartate = GDP + phosphate + N(6)-(1,2-dicarboxyethyl)-AMP. HAMAP MF_00011

Cofactor

Binds 1 magnesium ion per subunit By similarity. HAMAP MF_00011

Pathway

Purine metabolism; AMP biosynthesis via de novo pathway; AMP from IMP: step 1/2. HAMAP MF_00011

Subunit structure

Homodimer By similarity. HAMAP MF_00011

Subcellular location

Cytoplasm By similarity HAMAP MF_00011.

Sequence similarities

Belongs to the adenylosuccinate synthetase family.
