General annotation (Comments)

Function

Plays an important role in the de novo pathway of purine nucleotide biosynthesis. Catalyzes the first committed step in the biosynthesis of AMP from IMP By similarity. HAMAP-Rule MF_00011

Catalytic activity

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

Cofactor

Binds 1 magnesium ion per subunit By similarity.

Pathway

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

Subunit structure

Homodimer By similarity.

Subcellular location

Cytoplasm By similarity.

Sequence similarities

Belongs to the adenylosuccinate synthetase family.
