General annotation (Comments)

Catalytic activity

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

Pathway

Amino-acid biosynthesis; L-arginine biosynthesis; L-arginine from L-ornithine and carbamoyl phosphate: step 2/3.

Nitrogen metabolism; urea cycle; (N(omega)-L-arginino)succinate from L-aspartate and L-citrulline: step 1/1.

Subunit structure

Homotetramer By similarity.

Sequence similarities

Belongs to the argininosuccinate synthase family.
