comment
  • FUNCTION Part of a heterotetrameric complex that catalyzes the two-step biosynthesis of anthranilate, an intermediate in the biosynthesis of L-tryptophan. In the first step, the glutamine-binding beta subunit of anthranilate synthase (AS) provides the glutamine amidotransferase activity which generates ammonia as a substrate that, along with chorismate, is used in the second step, catalyzed by the large alpha subunit of AS to produce anthranilate.CATALYTIC ACTIVITY chorismate + L-glutamine = anthranilate + pyruvate + L-glutamate + H(+)PATHWAY Amino-acid biosynthesis; L-tryptophan biosynthesis; L-tryptophan from chorismate: step 1/5.SUBUNIT Heterotetramer consisting of two non-identical subunits: a beta subunit and a large alpha subunit.SUBCELLULAR LOCATION Expressed in roots and leaves.INDUCTION By chitin oligosaccharide elicitor and the phytopathogenic fungus Bipolaris oryzae.
