The roles of a light-dependent protochlorophyllide oxidoreductase (LPOR), and ATP-dependent dark operative protochlorophyllide oxidoreductase (DPOR) in chlorophyll biosynthesis

Chlorophyll is a green photosynthetic pigment, and photosynthesis drives the global carbon cycle. The reduction of protochlorophyllide (Pchlide) to chlorophyllide (Chlide) in the penultimate stage of biosynthesis of chlorophyll (Chl) is catalyzed by light-independent protochlorophyllide reducatse (DPOR), and the light-dependent protochlorophyllide oxidoreductase (LPOR). The search was done to all manuscript sections according to terms chlorophyll, a light-dependent protochlorophyllide oxidoreductase, ATP-dependent dark operative protochlorophyllide oxidoreductase, chlorophyll, photosynthesis and chlorophyllide. Within the framework of photosynthesis and chlorophyll, this review article was aimed to provide an overview of the functional studies in chlorophyll biosynthesis, protein crystal structure, disclosure of action mechanisms, and possible future available direction of LPOR and DPOR in the biosynthesis of chlorophyll.
