the enzyme converts not only all possible 1-hydroxycarotenoids in the spheroidene/1'-hydroxyspheroidene biosynthetic pathway of Rhodobacter capsulatus but also carotenoid intermediates leading to the formation of spirilloxanthin in a pathway which is absent in Rhodobacter capsulatus but present in related species. Hydroxycarotenoids not accepted by CrtF are 1'-hydroxy-3,4-didehydrolycopene, 1-hydroxy-zeta-carotene, 1,1'-dihydroxy-zeta-carotene both without the 7,8- and 7',8'-double bond and cyclic zeaxanthin. From all these complementation results the structural requirements of a substrate for CrtF can be established. The 1-hydroxy-carotenoid should be acyclic with a 5,6-double bond in conjugation with the central polyene chain. A 3,4-double bond is optional. The other end group can be quite variable without a negative impact on methylation, provided that it is not a fully desaturated psi-end group |
