Accepted name: demethylspheroidene O-methyltransferase
Reaction: S-adenosyl-L-methionine + demethylspheroidene = S-adenosyl-L-homocysteine + spheroidene

Other name(s): 1-hydroxycarotenoid O-methylase; 1-hydroxycarotenoid methylase; 1-HO-carotenoid methylase; CrtF
Systematic name: S-adenosyl-L-methionine:demethylspheroidene O-methyltransferase
Comments: In Rhodopseudomonas capsulata and Rubrivivax gelatinosus the enzyme is involved in biosynthesis of spheroidene [1,2,3]. In Rubrivivax gelatinosus the enzyme also catalyses the methylation of demethylspirilloxanthin to spirilloxanthin and the methylation of 3,4-didehydrorhodopin to anhydrorhodovibrin [2].
