Chlorophyllides: Preparation, Purification, and Application
Results reveal that light illumination, light intensity, δ-aminolevulinic acid, protochlorophyllide oxidoreductase, light-independent protochlorophyllide reductase, norflurazon, and water have positive effects on the production of chlorophyllide, whereas nitric oxide has a negative effect.
Protochlorophyllide reduction: mechanisms and evolutions
Protochlorophyllide (Pchlide) reductases are key enzymes in the process of chlorophyll biosynthesis. In this review, current knowledge on the molecular organization, substrate specificity and assembly of the light-dependent reduced nicotinamide adenine dinucleotide phosphate:Pchlide oxidoreductases are discussed.
