Argininosuccinic acid is a non-proteinogenic amino acid that is an important intermediate in the urea cycle. ^[1] It is also known as argininosuccinate.^[2]

Reactions

Some cells synthesize argininosuccinic acid from citrulline and aspartic acid and use it as a precursor for arginine in the urea cycle (or citrulline-NO cycle), releasing fumarate as a by-product to enter the TCA cycle. The enzyme that catalyzes the reaction is argininosuccinate synthetase.^[3]^[4]

Argininosuccinic acid is a precursor to fumarate in the citric acid cycle via argininosuccinate lyase.^[5]
