General annotation (Comments)

Function

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). Ref.1

Catalytic activity

Carotenoid psi-end group = carotenoid beta-end group.

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

Pathway

Carotenoid biosynthesis; beta-carotene biosynthesis.

Carotenoid biosynthesis; phytoene biosynthesis; all-trans-phytoene from geranylgeranyl diphosphate: step 1/1.

Subcellular location

Membrane; Multi-pass membrane protein Potential.

Induction

Strongly induced during mating of two strains of the opposite sex. Ref.2

Biotechnological use

Beta-carotene is a popular additive for butter, ice cream, orange juice and candies in the food industry. B.trispora is one of the microorganisms of choice for industrial production of this molecule. Ref.1

Sequence similarities

In the N-terminal section; belongs to the lycopene beta-cyclase family.

In the C-terminal section; belongs to the phytoene/squalene synthase family.
