>TIGR00032 argG argininosuccinate synthase; InterPro: IPR001518 Argininosuccinate synthase (6.3.4.5 from EC) (AS) is a urea cycle enzyme that catalyzes the penultimate step in arginine biosynthesis: the ATP-dependent ligation of citrulline to aspartate to form argininosuccinate, AMP and pyrophosphate , . In humans, a defect in the AS gene causes citrullinemia, a genetic disease characterised by severe vomiting spells and mental retardation. AS is a homotetrameric enzyme of chains of about 400 amino-acid residues. An arginine seems to be important for the enzyme's catalytic mechanism. The sequences of AS from various prokaryotes, archaebacteria and eukaryotes show significant similarity.; GO: 0004055 argininosuccinate synthase activity, 0005524 ATP binding, 0006526 arginine biosynthetic process.
