>gnl|CDD|197875 smart00788, Adenylsucc_synt, Adenylosuccinate synthetase.
           Adenylosuccinate synthetase plays an important role in
           purine biosynthesis, by catalyzing the GTP-dependent
           conversion of IMP and aspartic acid to AMP.
           Adenylosuccinate synthetase has been characterized from
           various sources ranging from Escherichia coli (gene
           purA) to vertebrate tissues. In vertebrates, two
           isozymes are present - one involved in purine
           biosynthesis and the other in the purine nucleotide
           cycle. The crystal structure of adenylosuccinate
           synthetase from E. coli reveals that the dominant
           structural element of each monomer of the homodimer is a
           central beta-sheet of 10 strands. The first nine strands
           of the sheet are mutually parallel with right-handed
           crossover connections between the strands. The 10th
           strand is antiparallel with respect to the first nine
           strands. In addition, the enzyme has two antiparallel
           beta-sheets, comprised of two strands and three strands
           each, 11 alpha-helices and two short 3/10-helices.
           Further, it has been suggested that the similarities in
           the GTP-binding domains of the synthetase and the p21ras
           protein are an example of convergent evolution of two
           distinct families of GTP-binding proteins. Structures of
           adenylosuccinate synthetase from Triticum aestivum and
           Arabidopsis thaliana when compared with the known
           structures from E. coli reveals that the overall fold is
           very similar to that of the E. coli protein.
