ID:PURA1_HUMAN DESCRIPTION: RecName: Full=Adenylosuccinate synthetase isozyme 1; Short=AMPSase 1; Short=AdSS 1; EC=6.3.4.4; AltName: Full=Adenylosuccinate synthetase, basic isozyme; AltName: Full=Adenylosuccinate synthetase, muscle isozyme; Short=M-type adenylosuccinate synthetase; AltName: Full=IMP--aspartate ligase 1; FUNCTION: Component of the purine nucleotide cycle (PNC), which interconverts IMP and AMP to regulate the nucleotide levels in various tissues, and which contributes to glycolysis and ammoniagenesis. Catalyzes the first committed step in the biosynthesis of AMP from IMP (By similarity). CATALYTIC ACTIVITY: GTP + IMP + L-aspartate = GDP + phosphate + N(6)-(1,2-dicarboxyethyl)-AMP. COFACTOR: Binds 1 magnesium ion per subunit (By similarity). PATHWAY: Purine metabolism; AMP biosynthesis via de novo pathway; AMP from IMP: step 1/2. SUBUNIT: Homodimer (By similarity). SUBCELLULAR LOCATION: Cytoplasm. TISSUE SPECIFICITY: Predominantly expressed in skeletal muscle and heart, as well as in several hematopoietic cell lines and solid tumors. SIMILARITY: Belongs to the adenylosuccinate synthetase family. SEQUENCE CAUTION: Sequence=AAH32039.1; Type=Frameshift; Positions=1; Sequence=CAD62614.1; Type=Erroneous initiation;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
