Argininosuccinate synthase

Gene

ass1

Organism
Xenopus tropicalis (Western clawed frog) (Silurana tropicalis)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at transcript leveli

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.By similarity

Catalytic activityi

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

Pathwayi: L-arginine biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes L-arginine from L-ornithine and carbamoyl phosphate.By similarity
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. no protein annotated in this organism
This subpathway is part of the pathway L-arginine biosynthesis, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-arginine from L-ornithine and carbamoyl phosphate, the pathway L-arginine biosynthesis and in Amino-acid biosynthesis.

Pathwayi: urea cycle

This protein is involved in step 1 of the subpathway that synthesizes (N(omega)-L-arginino)succinate from L-aspartate and L-citrulline.By similarity
Proteins known to be involved in this subpathway in this organism are:
  1. Argininosuccinate synthase (ass1)
