Fig. 19 in The scope of flavin-dependent reactions and processes in the model plant Arabidopsis thaliana

Fig. 19. Reaction catalyzed by squalene epoxidase. The reducing equivalents are delivered by NADPH, and therefore, the enzyme was assigned to subclass A of flavin-dependent monooxygenases (Paul et al., 2021). Similar to zeaxanthine epoxidase the enzyme forms an unusual epoxide (see Fig. 31).
