Functioni

Bifunctional enzyme that catalyzes the reactions from geranylgeranyl diphosphate to phytoene (phytoene synthase) and lycopene to beta-carotene via the intermediate gamma-carotene (lycopene cyclase).1 Publication

Catalytic activityi

Carotenoid psi-end group = carotenoid beta-end group.
2 geranylgeranyl diphosphate = 15-cis-phytoene + 2 diphosphate.

Pathway:ibeta-carotene biosynthesis

This protein is involved in the pathway beta-carotene biosynthesis, which is part of Carotenoid biosynthesis.
View all proteins of this organism that are known to be involved in the pathway beta-carotene biosynthesis and in Carotenoid biosynthesis.

Pathway:iphytoene 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. Bifunctional lycopene cyclase/phytoene synthase (carRA)
This subpathway is part of the pathway phytoene biosynthesis, which is itself part of Carotenoid biosynthesis.
