comment
  • FUNCTION Catalyzes the conversion of ent-copalyl diphosphate to the gibberellin precursor ent-kaur-16-ene.CATALYTIC ACTIVITY ent-copalyl diphosphate = ent-kaur-16-ene + diphosphateCOFACTOR Binds 3 Mg(2+) ions per subunit.PATHWAY Plant hormone biosynthesis; gibberellin biosynthesis.SUBCELLULAR LOCATION Highly expressed in panicles and at lower levels in leaves and stems.DOMAIN The Asp-Asp-Xaa-Xaa-Asp/Glu (DDXXD/E) motif is important for the catalytic activity, presumably through binding to Mg(2+).MISCELLANEOUS Plants lacking KS1 display a dwarf phenotype with normal root development, but severe stunting of shoots in seedlings, dark green leaves and failure to initiate flowering. This phenotype can be rescued by treatment with exogenous gibberellin.SIMILARITY Belongs to the terpene synthase family.SEQUENCE CAUTION Sequencing errors.
