Tetrapyrroles are macrocyclic molecules with various structural variants and multiple
functions in Prokaryotes and Eukaryotes. Present knowledge about the metabolism of …

This Current Topic focuses on light-dependent protochlorophyllide oxidoreductase (POR,
EC 1.3. 1.33). POR catalyzes the penultimate reaction of chlorophyll biosynthesis, ie, the …

Marine and terrestrial photosynthesis exhibit a schism in the accessory chlorophyll (Chl) that
complements the function of Chl a: Chl b for green plants versus Chl c for most eukaryotic …

Chlorophyll biosynthesis, crucial to life on Earth, is tightly regulated because its precursors
are phototoxic. In flowering plants, the enzyme light-dependent protochlorophyllide …

Peanut is an important edible oil crop plant whose quality and yield are greatly affected by
drought. The process and molecular mechanisms of recovery from drought are also critical …

Chloroplast biogenesis is a complex process that is integrated with plant development,
leading to fully differentiated and functionally mature plastids. In this work, we used electron …

Etioplasts are photosynthetically inactive plastids that accumulate when light levels are too
low for chloroplast maturation. The etioplast inner membrane consists of a paracrystalline …

Oxygenic photosynthesis requires chlorophyll (Chl) for the absorption of light energy, and
charge separation in the reaction center of photosystem I and II, to feed electrons into the …

Enzymatic photocatalysis is seldom used in biology. Photocatalysis by light-dependent
protochlorophyllide oxidoreductase (LPOR)—one of only a few natural light-dependent …

The photoenzyme protochlorophyllide oxidoreductase (POR) is an important enzyme for
understanding biological H‐transfer mechanisms. It uses light to catalyse the reduction of …
