    Protein Summary

    The gene TM1780 from Thermotoga maritima encodes argininosuccinate synthase PF00764 COG0137, a member of N-type ATP pyrophosphatases.  The protein belongs to the class of alpha and beta proteins (a+b) and reveals adenine nucleotide alpha hydrolase-like fold SCOP52373. The argininosuccinate synthase is a urea cycle enzyme that catalyzes the penultimate step in arginine biosynthesis, which is the ATP-dependent ligation of citrulline to aspartate to form argininosuccinate, AMP and pyrophosphate. The biological unit of the enzyme is homotetramer.  The sequences of this enzyme from various prokaryotes, archaebacteria and eukaryotes show significant similarity.  The crystal structure of human homologue is available 2NZ2.
