Ferredoxins are iron-sulfur containing proteins performing electron transfer in a wide variety of biological systems and processes. They include roles in photosynthesis in chloroplasts. Ferredoxins are classified structurally by the iron-sulfur clustered centers they contain. Fe2S2 clusters (Figure 5.50) are found in chloroplast membranes and can donate electrons to glutamate synthase, nitrate reductase, and sulfite reductase and serve as electron carriers between reductase flavoproteins and bacterial dioxygenase systems. Adrenodoxin is a soluble human Fe2S2 ferredoxin (also called ferredoxin 1) serving as an electron carrier (to cytochrome P450) in mitochondrial monooxygenase systems. Fe4S4 ferredoxins are subdivided as low and high potential ferredoxins, with the latter ones functioning in anaerobic electron transport chains.

Diatoms are ubiquitous marine photosynthetic eukaryotes that are responsible for about 20% of global photosynthesis.
(矽藻是廣泛存在於海洋中的光合作用真核生物,約佔全球光合作用總量的 20%。)

Ferredoxin (鐵氧化還原蛋白)
Ferritin is an intracellular iron-storage protein found in almost all living organisms, from bacteria to higher plants and animals. It is a globular protein complex with 24 subunits and is the primary intracellular iron-storage protein in eukaryotes and prokaryotes. Ferritin functions to keep iron in a soluble and non-toxic form. Its ability to safely store iron and release it in a controlled fashion allow it to act like the prime iron buffer and solubilizer in cells – keeping the concentration of free iron from going to high or falling too low. Ferritin is located in the cytoplasm in most tissues, but it is also found in the serum acting as an iron carrier. Ferritin that doesn’t contain any iron is known as apoferritin.

Ferritin forms a shell consisting
of 24 heavy and light chains that are folded in a four-helix bundle with
threefold and fourfold channels and can bind up to 4500 iron atoms in the form of ferrihydrite
(5Fe2O3•9H2O).

cofactor (輔因子)
An organic molecule or ion (usually a metal ion) that is required by an enzyme for its activity. (一種酵素在執行其活性時所需的有機分子或離子,通常為金屬離子。)
It may be attached either loosely (coenzyme) or tightly (prosthetic group). (它可能以鬆散的方式結合 (coenzyme 輔酶),或是 以緊密的方式結合 (prosthetic group 輔基)。)
