Inhibitors

Inhibitors Comment Organism Structure
additional information no effect of sugars and amino sugars on violaxanthin de-epoxidase is observed, but epoxidation of zeaxanthin to violaxanthin is inhibited, incubation with amino sugars under a 6 d photoperiod enhances the inhibitory effect, zeaxanthin epoxidation is completely inhibited under such conditions, overview Lemna trisulca
