| 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]. |
