【 摘 要 】

Protochlorophyllide reductase (EC 1.6.99.1) catalyses the light-dependent reduction of protochlorophyllide to chlorophyllide. Evidence has been obtained for the possible involvement of FAD in this reaction: (i) protochlorophyllide reductase is inhibited by quinacrine and trifluoperazine at micromolar levels consistent with their action as flavoprotein antagonists; (ii) preparations containing protochlorophyllide reductase can mediate cytochrome c reduction; (iii) in protochlorophyllide reductase-rich etioplast membranes FAD co-purifies with the enzyme.
