| 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. |
| Catalytic activity | RHEA:15753: GTP + IMP + L-aspartate = GDP + 2 H(+) + N(6)-(1,2-dicarboxyethyl)-AMP + phosphate
EC 6.3.4.4 |
| Cofactor | Mg(2+) Note: Binds 1 Mg(2+) ion per subunit. |
| Pathway | Purine metabolism; AMP biosynthesis via de novo pathway; AMP from IMP: step 1/2. |
| Subunit | Homodimer. |
| Subcellular location | Cytoplasm. |
| Similarity | Belongs to the adenylosuccinate synthetase family. |
