Ferredoxins (from Latin ferrum: iron + redox, often abbreviated "fd") are iron–sulfur proteins that mediate electron transfer in a range of metabolic reactions. The term "ferredoxin" was coined by D.C. Wharton of the DuPont Co. and applied to the "iron protein" first purified in 1962 by Mortenson, Valentine, and Carnahan from the anaerobic ...

铁氧还蛋白[1] （英語： Ferredoxin）是一类在多种代谢反应中介导 电子转移 的 铁硫蛋白。 “铁氧还蛋白”这个词由杜邦公司的D·C·沃顿所创，并将此名应用于默顿森、瓦伦丁与卡纳汉从 厌氧菌 巴斯德梭菌 中首次纯化出的“铁蛋白”上 [2][3]。 ^ Mortenson LE, Valentine RC, Carnahan JE.

Ferredoxins are small globular Fe–S cluster-containing proteins known to be involved in various electron transfer processes in bacteria, mammals and plants (50–53). The ferredoxin (Fdx) coded by the isc operon is a monomeric 12-kDa protein which contains a stable [2Fe–2S] cluster.

褐色，缩写Fd，是L．E．Mort-enson等在1962年从巴氏梭菌（Clostridium paste-urianum）分离到的，同年四川邦夫和D．I．Arnon指出，它与 光合作用 有关系。 广泛分布于细菌、藻类、高等植物中。 细菌Fd的分子量约6千，植物的约1万3千。 铁原子和 半胱氨酸 侧链的SH基和无机硫结合。 使成酸性，就游离出铁离子和硫化氢。 一级结构已经确定，用X-衍射进行了三维结构的分析。 氧化还原电位 极低，Eo′为-0.42V。 在光合成系统中，通过 叶绿体，为光还原，通过Fd-NADP …

2022年10月24日 · Ferredoxins are widespread iron–sulfur (Fe–S)-cluster-containing enzymes required for a wide variety of electron transfer reactions. Consistently, mammals possess two distantly related...

2024年9月1日 · Ferredoxins are proteins found in all biological kingdoms and are involved in essential biological processes including photosynthesis, lipid metabolism, and biogeochemical cycles. Ferredoxins are classified into different groups based on the iron-sulfur (Fe-S) …

Ferredoxins are small, FeS-binding proteins that mediate electron transfer in a range of metabolic reactions. Cyanobacteria carry several different types of ferredoxins in varying numbers depending on the species.

2018年2月28日 · Ferredoxin (Fd) is a small soluble iron-sulfur protein essential in almost all oxygenic photosynthetic organisms. It contains a single [2Fe-2S] cluster coordinated by four cysteine ligands.

Ferredoxin (Fd) is a small [2Fe-2S] cluster-containing protein found in all organisms performing oxygenic photosynthesis. Fd is the first soluble acceptor of electrons on the stromal side of the chloroplast electron transport chain, and as such is pivotal to determining the distribution of these electrons to different metabolic reactions.

1994年1月1日 · Ferredoxins (Fds) are simple iron-sulfur proteins that contain pros- thetic groups composed of iron and sulfur atoms and play a functional role in electron transfer processes relevant for SRB metabolism (phosphor- oclastic reaction and sulfite reduction).
