The Light-Dependent and Light-Independent Reduction of Protochlorophyllide a to Chlorophyllide a

B. Schoefs1

Two different pathways for protochlorophyllide a (Pchlide) reduction in photosynthetic organisms have been proved: one is strictly light-dependent whereas the second is light-independent. Both pathways occur in all photosynthetic cells except in angiosperms which form chlorophyll only through the light-dependent pathway. Most cells belonging to Eubacteria (i.e., the anoxygenic photosynthetic bacteria) synthesize bacteriochlorophyll through the light-independent pathway. This review deals with the physiological, biochemical, and molecular biological features of molecules involved in both pathways of Pchlide reduction.

Additional key words: bacteriochlorophyll; bacteriochlorophyllide; cysteine; chlorophyll; greening; lysine; methionine; valine; tyrosine
