- GenePDS1
- StatusUniProtKB reviewed (Swiss-Prot)
- Amino acids570 (go to sequence)
- Protein existenceEvidence at protein level
- Annotation score5/5
Function
function
Converts phytoene into zeta-carotene via the intermediary of phytofluene by the symmetrical introduction of two double bonds at the C-11 and C-11' positions of phytoene with a concomitant isomerization of two neighboring double bonds at the C9 and C9' positions from trans to cis.
Catalytic activity
- 2 a plastoquinone + 15-cis-phytoene = 9,9',15-tri-cis-zeta-carotene + 2 a plastoquinol
Cofactor
Pathway
Carotenoid biosynthesis; lycopene biosynthesis.
