Argininosuccinat-Synthase
Die Argininosuccinat-Synthase ist ein essentielles Enzym im Harnstoffzyklus, das die kovalente Bindung von Citrullin und Aspartat zu Argininosuccinat katalysiert, wodurch Ammoniak entfernt und in eine ungiftige Form umgewandelt wird.

Argininosuccinic acid (ASA) is a chemical compound that plays a crucial role in the urea cycle, the metabolic pathway responsible for removing excess nitrogen from the body in the form of urea. Inherited deficiencies in the enzymes involved in the urea cycle, such as argininosuccinate synthetase and argininosuccinate lyase, can lead to an accumulation of ASA in the blood, resulting in a genetic disorder known as argininosuccinic aciduria.
Argininosuccinic Aciduria
Argininosuccinic aciduria is a rare inherited metabolic disorder characterized by the body's inability to properly break down argininosuccinic acid due to a deficiency of the enzyme argininosuccinate lyase, leading to an accumulation of this compound and other toxic substances in various bodily fluids and tissues, which can cause mental and physical impairments if left untreated.
