5-aminoimidazole-4-(N-succinylcarboxamide)
ribonucleotide (SAICAR) synthase. A subfamily of SAICAR
synthetases represented by the Thermotoga maritima (Tm)
enzyme and E. coli PurC. SAICAR synthetase catalyzes the
seventh step of the de novo biosynthesis of purine
nucleotides (also reported as eighth step). It converts
5-aminoimidazole-4-carboxyribonucleotide (CAIR), ATP,
and L-aspartate into
5-aminoimidazole-4-(N-succinylcarboxamide)
ribonucleotide (SAICAR), ADP, and phosphate.

>gnl|CDD|107206 cd01563, Thr-synth_1, Threonine synthase is a pyridoxal phosphate
(PLP) dependent enzyme that catalyses the last reaction
in the synthesis of threonine from aspartate. It
proceeds by converting O-phospho-L-homoserine (OPH) into
threonine and inorganic phosphate. In plants, OPH is an
intermediate between the methionine and
threonine/isoleucine pathways. Thus threonine synthase
competes for OPH with cystathionine-gamma-synthase, the
first enzyme in the methionine pathway. These enzymes
are in general dimers. Members of this CD, Thr-synth_1,
are widely distributed in bacteria, archaea and higher
plants..
