CC   -!- FUNCTION: Catalyzes the reaction from prephytoene diphosphate to
CC       phytoene. Probably part of an operon y4aABCD involved in the
CC       synthesis of an isoprenoid compound.
CC   -!- CATALYTIC ACTIVITY: 2 geranylgeranyl diphosphate = 15-cis-phytoene
CC       + 2 diphosphate.
CC   -!- SIMILARITY: Belongs to the phytoene/squalene synthase family.
