comment
  • FUNCTION Catalyzes the conversion of geranylgeranyl diphosphate to phytoene. Mediates the first committed step in carotenoid biosynthesis.CATALYTIC ACTIVITY 2 (2E,6E,10E)-geranylgeranyl diphosphate = 15-cis-phytoene + 2 diphosphateSUBCELLULAR LOCATION Expressed in leaves (PubMed:15247400, PubMed:18326788). Highly expressed in developing leaves. Expressed at low levels in roots (PubMed:18326788).INDUCTION Induced by salt stress and abscisic acid (ABA) in roots.SIMILARITY Belongs to the phytoene/squalene synthase family.
