Protein attributes
| Sequence length | 456 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Plays an important role in the de novo pathway and in the salvage pathway of purine nucleotide biosynthesis. Catalyzes the first commited step in the biosynthesis of AMP from IMP. Ref.2 |
| Catalytic activity | GTP + IMP + L-aspartate = GDP + phosphate + N(6)-(1,2-dicarboxyethyl)-AMP. |
| Cofactor | Binds 1 magnesium ion per subunit By similarity. |
| Enzyme regulation | Inhibited competitively by AMP and IMP and non-competitively by fructose 1,6-bisphosphate. |
| Pathway | Purine metabolism; AMP biosynthesis via de novo pathway; AMP from IMP: step 1/2. |
| Subunit structure | Homodimer By similarity. |
| Subcellular location | |
| Sequence similarities | Belongs to the adenylosuccinate synthetase family. |
| Biophysicochemical properties | Kinetic parameters: KM=15 µM for GTP Ref.2 KM=12 µM for IMP KM=950 µM for L-aspartate pH dependence: Optimum pH is 6.6-6.9. |
