Protein
Phytoene synthase
Gene
crtB, RCAP_rcc00680
Organism
Rhodobacter capsulatus (strain ATCC BAA-309 / NBRC 16581 / SB1003)
Status
Reviewed - Annotation score: 2 out of 5 - Protein inferred from homologyi

Functioni

Involved in the biosynthesis of carotenoids. Catalyzes the condensation of two molecules of geranylgeranyl diphosphate (GGPP) to give prephytoene diphosphate (PPPP) and the subsequent rearrangement of the cyclopropylcarbinyl intermediate to yield phytoene By similarity.

Cofactori

ATP. ATP is required for the transferase activity but it does not seem to be hydrolyzed during the reaction By similarity.
Manganese or magnesium By similarity.
