Functioni

One of the enzymes of the urea cycle, the metabolic pathway transforming neurotoxic amonia produced by protein catabolism into inocuous urea in the liver of ureotelic animals. Catalyzes the formation of arginosuccinate from aspartate, citrulline and ATP and together with ASL it is responsible for the biosynthesis of arginine in most body tissues.3 Publications

Catalytic activityi

ATP + L-citrulline + L-aspartate = AMP + diphosphate + N(omega)-(L-arginino)succinate.3 Publications

Pathwayi: L-arginine biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes L-arginine from L-ornithine and carbamoyl phosphate.3 Publications
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. no protein annotated in this organism
  2. Argininosuccinate synthase (ASS1)
  3. Argininosuccinate lyase (ASL)
This subpathway is part of the pathway L-arginine biosynthesis, which is itself part of Amino-acid biosynthesis.

Involvement in diseasei

Citrullinemia 1 (CTLN1)16 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionThe classic form of citrullinemia, an autosomal recessive disease characterized primarily by elevated serum and urine citrulline levels. Ammonia intoxication is another manifestation. It is a disorder of the urea cycle, usually manifesting in the first few days of life. Affected infants appear normal at birth, but as ammonia builds up in the body they present symptoms such as lethargy, poor feeding, vomiting, seizures and loss of consciousness. Less commonly, a milder form can develop later in childhood or adulthood.
