1.3.99.30	15-cis-phytoene + 5 acceptor	a decisive reaction for the formation of monocyclic or bicyclic products is the desaturation sequence to lycopene and further on to 3,4-didehydrolycopene. In the nontransformed strain, cyclization of lycopene, which directs the metabolic flux towards astaxanthin, is the dominating reaction. When the gene encoding phytoene desaturase is overexpressed, the five-step desaturation to 3,4-didehydrolycopene is intensified, resulting in an accumulation of torulene and 3-hydroxy-3'-4'-didehydro-beta-psi-caroten-4-one as subsequent products	Phaffia rhodozyma	all-trans-3,4-didehydrolycopene + 5 reduced acceptor	-	?	413171
