細胞色素複合體 （cytochrome complex）簡稱 細胞色素c （cyt c），是一種血红素蛋白（hemoprotein），屬於“ 细胞色素c家族 （英语：Cytochrome c family） ” [1]。 細胞色素c會與 粒線體 內膜輕微連接，結構鬆散而微小的它和其他 細胞色素 不同，是一種高度可溶性蛋白，在水中的可溶性達每公升100克。 細胞色素c是 電子傳遞鏈 不可或缺的元件，負責攜帶一粒電子，在 複合物III 和 複合物IV 之間傳遞。 此外，它能夠接受 氧化 和 還原反應，但不與 氧 結合。 在人體 …

Cyt c，一种含有金属蛋白的血红素，位于线粒体的膜间空间，在病理状态下释放到血流中。 线粒体中cyt c的释放是激活细胞死亡途径的关键主动步骤。 循环中的cyt c水平代表了心力衰竭和化学疗法复苏后线粒体损伤的新型体内标记。

2010年6月1日 · This review deals exclusively with the cyt c maturation pathway found in α- and γ-proteobacteria, Deinococcus species, mitochondria of plants and red algae, and archaea, termed the Ccm system or System I [7].

2015年6月11日 · Biomolecule cytochrome c (Cty c), a small molecule of a chain of amino acids with extraordinary electron transport, was helically wrapped around a semiconductive single-wall carbon nanotube...

In this review, we explore the development of Cyt c as an anticancer drug by identifying cancer types that would be receptive to the cytotoxicity of the protein and factors that can be finetuned to enhance its apoptotic potency.

2012年8月2日 · Multi-walled carbon nanotube (MWCNT)-modified electrodes can promote the direct electron transfer (DET) of cytochrome c (Cyt c). There are several possible mechanisms that explain the DET of Cyt c.

利用电化学和紫外-可见(UV-Vis)吸收光谱研究了pH 和Au NPs 对细胞色素c (Cyt c)结构的影响. UV-Vis 吸收 光谱结果表明, pH 为7.5-3.0 时, Cyt c 和Cyt c-Au NPs 复合物的结构没有发生明显变化.

2020年4月1日 · Cyt c acts as an electron carrier between complex III (bc1 complex) and complex IV (cytochrome c oxidase) in the ETC resulting in efficient ATP production at complex V (ATP synthase). Under basal conditions, Cyt c is phosphorylated in a tissue-specific manner.

2021年12月20日 · We describe cryo-electron microscopy (cryo-EM) structures of CcsBA, a bifunctional heme transporter and cytochrome c (cyt c) synthase. Models built from the cryo-EM densities show that CcsBA is...

2021年9月25日 · Background: Cytochrome c (Cyt c) is a key biomarker for early apoptosis, and many methods were designed to detect its release from mitochondria. For a proper evaluation of these programed cell death mechanisms, fluorescent nanoparticles are excellent candidates due to their valuable optical properties.
