Activating Compound

Activating Compound Comment Organism Structure
decyl-plastoquinone enhances zeta-carotene desaturase activity significantly and increases the ratio of lycopene to neurosporene among the reaction products. Quinones other than decyl-plastoquinone and decyl-ubiquinone do not stimulate Capsicum annuum

zeta-carotene + 2 quinone Capsicum annuum zeta-carotene desaturase has no preference for certain isomers. The nature of the isomers formed during catalysis depends strictly on the isomeric composition of the substrate. Different lycopene isomers are formed, including substantial amounts of the all-trans form, together with 7,7',9,9'-tetracis prolycopene via the corresponding neurosporene isomers lycopene + 2 quinol
