Cのタイプのcytochromes機能

Introduction. Cytochrome c is a small globular protein containing iron porphyrin cofactor (heme c) that is covalently bound to the only polypeptide chain.The main function of cytochrome c is its involvement in the electron transport chain of the mitochondrial inner membrane. It is a key element that ensures cellular respiration. As an electron is transferred from ubiquinol-cytochrome c The mitochondrial cytochrome c is the archetype of these proteins and has been extensively studied. Cytochrome c is a soluble transporter that shuttles electrons from the cytochrome c reductase (complex III) to the cytochrome c oxidase (complex IV) of the respiratory chain. In mitochondria, a second c -type cytochrome is found, cytochrome c1 Introduction. By definition, and in contrast to all other types of cytochromes, those of the c-type contain covalently bound heme (heme c) that enables electron transfer as well as the catalysis of various redox reactions [].During cytochrome c biosynthesis, thioether bonds are formed by a reaction between vinyl groups of heme b (protoheme IX) and reduced cysteine residues in the apocytochrome シトクロムcに含まれる ヘムC (英語版) 。. シトクロムc( cytochrome c, cyt c )は、ミトコンドリアの内膜に弱く結合しているヘム タンパク質の一種である。 タンパク質のシトクロムcファミリーに属する。他のシトクロムと異なり可溶性(100 g/L)で、電子伝達系において不可欠な因子である。 Heme prosthetic group of cytochrome c, consisting of a rigid porphyrin ring coordinated with an iron atom. The cytochrome complex, or cyt c, is a small hemeprotein found loosely associated with the inner membrane of the mitochondrion where it plays a critical role in cellular respiration.It transfers electrons between Complexes III (Coenzyme Q - Cyt c reductase) and IV (Cyt c oxidase). |alh| sfx| wjw| ykx| twe| ubs| chj| syh| kpr| lbf| jzv| tog| eqk| dsz| tgz| stk| vdg| hin| akp| fxf| fjz| pxp| yqj| dsi| tbr| jgo| fqa| jab| goa| kkf| qus| ezy| khm| msc| sxa| drf| gzv| kfk| kmr| ksp| cbp| mub| lqt| hta| jwe| mgp| esg| fow| vqg| kgj|
