BRITE hierarchy
Sysname
S-adenosyl-L-methionine:demethylspheroidene O-methyltransferase
Reaction(IUBMB)
S-adenosyl-L-methionine + demethylspheroidene = S-adenosyl-L-homocysteine + spheroidene [RN:R07535]
Reaction(KEGG)
Substrate
S-adenosyl-L-methionine [CPD:C00019];
demethylspheroidene [CPD:C15898]
Product
S-adenosyl-L-homocysteine [CPD:C00021];
spheroidene [CPD:C15900]
Comment
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].
