Organism
Zea mays (Maize)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the reaction from prephytoene diphosphate to phytoene.

Catalytic activityi

2 geranylgeranyl diphosphate = 15-cis-phytoene + 2 diphosphate.

Pathwayi: phytoene biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes all-trans-phytoene from geranylgeranyl diphosphate.
Proteins known to be involved in this subpathway in this organism are:
  1. Phytoene synthase, chloroplastic (Y1)
This subpathway is part of the pathway phytoene biosynthesis, which is itself part of Carotenoid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes all-trans-phytoene from geranylgeranyl diphosphate, the pathway phytoene biosynthesis and in Carotenoid biosynthesis.
