BIOLOGICAL ACTIVITY
The transfer of crtB gene from Erwinia uredovora in mammalian cells produced phytoene, and the cells were protective against oxidative stress and H-ras induced transformation (Ref. 1205).
The cancer preventive activity of phytoene was confirmed in phytoene producing mammalian cells (Ref. 1207).
Transgenic mice carrying the phytoene synthase gene crtB produce phytoene and induce connexin 26 (Ref. 1349).

CHEMICAL SYNTHESIS

METABOLISM
Phytoene is the first colorless carotenoid, which is formed form two molecules of geranylgeranyl diphosphate (GGPP) by phytoene synthase in all carotenogenic organisms (Ref. 1001/1029/1030). This reaction is reported to be a rate-limiting step for carotenoid biosynthesis in a higher plant and a carotenogenic bacterium (Ref. 1016/1031). All carotenoids, except for C30 special ones, are synthesized from phytoene as the starting carotenoid substrate (Ref. 1003/1004/1005).
Chloroflexus aurantiacus (green filamentous photosynthetic bacterium) accumulates phytoene in the culture with 2-hydroxybiphenyl, and this compound inhibits carotenoid formation by inhibiting the flow of electrons liberated in the course of the desaturase reaction (Ref. 1166).
The genes from Xanthophyllomyces dendrorhous (crtYB) (Ref. 1172), Mucor circinelloides (carRP) (Ref. 1173), and Phycomyces blakesleeanus (carRA) (Ref. 1174) (fungus) encode a bifunctional protein involved phytoene synthase activity located in C-terminus domain and lycopene cyclase activity located in N-terminus domain.
An Escherichia coli transformant carrying the Erwinia uredovora crtE and crtB genes (Ref. 0201/1002).

GENETIC INFORMATION
Phytoene synthase genes (crtB or psy), which mediate the formation of phytoene from GGPP, have been cloned from the photosynthetic bacteria Rhodobacter species (Ref. 1032/1033), the nonphotosynthetic bacteria Erwinia species (Erwinia uredovara and E. herbicola) (Ref. 0201/0233/1034) and Thermus thermophilus (Ref. 1031), the cyanobacterium Synechococcus PCC7942 (Ref. 1029), the fungus Neurospora crassa (Ref. 1035), and higher plants such as tomato and red pepper (Ref. 1036/1037/1038/1039).
In tomato, PSY1 transcripts predominate in seedlings and in late stages of fruit ripeing, whereas PSY2 transcripts are relatively more abundant in mature leaves (Ref. 1036/1186/1190).
NOTE
Biotechnological achievement has been made in metabolic engineering of caroteoids in animal cells, by the group of H. Nishino in 1995, i. e., a transgenic mammalian cells, which accumulates phytoene, has been constructed by expressing the Erwinia phytoene synthase gene crtB (Ref. 1028).
