1-hydroxylycopene + acceptor | 33% conversion. The 3,4-desaturation reaction can only occur with mono-1-hydroxy carotenoids at a Psi-end group or with 1,1'-dihydroxy derivatives carrying a 3'4'-double bond. In addition, 1-hydroxy-zeta-carotene could also be converted by the desaturase. Enzyme kinetic studies show a substrate preference of 1-hydroxyneurosporene over 1-hydroxyycopene | Rubrivivax gelatinosus | 1-hydroxy-3,4-didehydrolycopene + reduced acceptor | - |
