1.3.99.40	physiological function	a gene disruption mutant does not produce detectable synechoxanthin, but has otherwise essentially normal carotenoid contents. Growth rate under standard conditions is identical to wild-type	745209	
1.3.99.40	physiological function	in Thiodictyon sp., lycopene cyclase CrtY produces gamma-carotene as the only product. gamma-Carotene desaturase methyltransferase CrtU produces carotenoids with chi-rings which are further transformed to final product okenone	-, 745040
