What is Kinetics of Violaxanthin De-epoxidation by Violaxanthin De-epoxidase, a Xanthophyll Cycle Enzyme, Is Regulated by Membrane Fluidity in Model Lipid Bilayers about?
This paper describes violaxanthin de‐epoxidation in model lipid bilayers. Unilamellar egg yolk phosphatidylcholine (PtdCho) vesicles supplemented with monogalactosyldiacylglycerol were found to be a suitable system for studying this reaction. Such a system resembles more the native thylakoid membrane and offers better possibilities for studying kinetics and factors controlling de‐epoxidation of violaxanthin than a system composed only ofmonogalactosyldiacylglycerol and is commonly used in xanthophyll cycle studies. The activity of violaxanthin de‐epoxidase (VDE) strongly depended on the ratio of monogalactosyldiacylglycerol to PtdCho in liposomes. The mathematical model of violaxanthin de‐epoxidation was applied to calculate the probability of violaxanthin to zeaxanthin conversion at different phases of de‐epoxidation reactions. Measurements of deepoxidation rate and EPR‐spin label study at different temperatures revealed that dynamic properties of the membrane are important factors that might control conversion of violaxanthin to antheraxanthin. A model of the molecular mechanism of violaxanthin de‐epoxidation where the reversed hexagonal structures (mainly created by monogalactos
