Protein
4,4'-diapophytoene synthase
Organism
Staphylococcus aureus (strain bovine RF122 / ET3-1)
Function
Involved in the biosynthesis of the yellow-orange carotenoid staphyloxanthin, which plays a role in the virulence via its protective function against oxidative stress. Catalyzes the head-to-head condensation of two molecules of farnesyl diphosphate (FPP) into the colorless C(30) carotenoid 4,4'-diapophytoene (dehydrosqualene).
Similarity
Belongs to the phytoene/squalene synthase family. CrtM subfamily.
