Biol. Chem. 277:40536-40543(2002). CC -!- FUNCTION: Plays an important role in the de novo pathway of purine CC nucleotide biosynthesis. CC -!- CATALYTIC ACTIVITY: GTP + IMP + L-aspartate = GDP + phosphate + 6- CC N-(1,2-dicarboxyethyl)-AMP. CC -!- COFACTOR: Binds 1 magnesium ion per subunit. CC -!- PATHWAY: Nucleotide biosynthesis; AMP biosynthesis; AMP from IMP: CC step 1/2. CC -!- SUBUNIT: Homodimer. CC -!- SUBCELLULAR LOCATION: Cytoplasm. Membrane; peripheral membrane CC protein. Note=Partially associated with particulate fractions. CC -!- ALTERNATIVE PRODUCTS: CC Event=Alternative splicing; Named isoforms=2; CC Name=1; CC IsoId=P28650-1; Sequence=Displayed; CC Name=2; CC IsoId=P28650-2; Sequence=VSP_008422; CC Note=No experimental confirmation available; CC -!- TISSUE SPECIFICITY: High levels in muscle. CC -!- SIMILARITY: Belongs to the adenylosuccinate synthetase family.
