Compound as reactive (1)

5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxylate + L-aspartate + ATP → 5'-phosphoribosyl-4-(N-succinocarboxamide)-5-aminoimidazole + H⁺ + phosphate + ADP

Compound as product (2)

N⁵-carboxyaminoimidazole ribonucleotide → 5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxylate

5-amino-1-(5-phospho-β-D-ribosyl)imidazole + ATP + CO2 + H2O → ADP + H+ + phosphate + 5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxylate

Reversible reaction (1)

2 H⁺ + 5-amino-1-(5-phospho-D-ribosyl)imidazole-4-carboxylate ↔ 5-amino-1-(5-phospho-β-D-ribosyl)imidazole + CO₂
