Abstract: NADPH:protochlorophyllide oxidoreductase (POR) is a key enzyme for the light-induced greening of etiolated angiosperm plants. It belongs to the ‘RED’ family of reductases, epimerases and dehydrogenases. All POR proteins characterized so far contain evolutionarily conserved… read more here.

Abstract: Light-dependent protochlorophyllide oxidoreductase is one of the few known enzymes that require a quantum of light to start their catalytic cycle. Upon excitation, it uses NADPH to reduce the C17–C18 in its substrate (protochlorophyllide) through… read more here.

DOI: 10.15835/nbha49312456
Abstract: 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… read more here.

DOI: 10.3390/ijms24010307
Abstract: Light-dependent protochlorophyllide oxidoreductase (LPOR) is a chlorophyll synthetase that catalyzes the reduction of protochlorophyllide (Pchlide) to chlorophyllide (Chlide) with indispensable roles in regulating photosynthesis processes. A recent study confirmed that thylakoid lipids (TL) were able… read more here.
