| cytochrome P-450SCC | Cholesterol monooxygenase (side chain cleaving). Origin: 450 nm, the absorption maximum that the CO compound of the reduced pigment exhibits (05 Mar 2000) |
|---|---|
| cytochrome peroxidase | A haemoprotein enzyme catalyzing the reaction between H2O2 and 2 ferrocytochrome c to yield 2ferricytochrome c and 2H2O. (05 Mar 2000) |
| cytochrome reductase | <enzyme> A flavoprotein that catalyses the reduction of haem-thiolate-dependent monooxygenases and is part of the microsomal hydroxylating system. Its physiological acceptor is probably cytochrome p-450. Chemical name: NADPH:ferrihemoprotein oxidoreductase Registry number: EC 1.6.2.4 (12 Dec 1998) |
| cytochrome reductases | <enzyme> Registry number: EC 1.6.2. (12 Dec 1998) |
| cytochrome system | The mitochondrial electron transport chain. (18 Nov 1997) |
| cytochrome-c oxidase | <enzyme> An enzyme complex of the inner mitochondrial membrane that catalyses the reaction between ferrocytochrome c and oxygen to yield ferricytochrome c and water. It is associated with the pumping of protons and the resultant phosphorylation of ADP to ATP. The reaction is the terminal event in the electron transport scheme by which oxygen is used for fuel combustion. It is a part of Complex IV of the respiratory chain. A deficiency of one or more of the polypeptides of this complex results in neuronal loss in brain leading to psychomotor retardation and neurodegenerative disease. Synonym: cytochrome aa3, indophenol oxidase, indophenolase. Chemical name: Ferricytochrome-c:oxygen oxidoreductase Registry number: EC 1.9.3.1 (12 Dec 1998) |
| cytochrome-c peroxidase | <enzyme> A haemprotein which catalyses the oxidation of ferrocytochrome c to ferricytochrome c in the presence of hydrogen peroxide. Chemical name: Ferrocytochrome c:hydrogen-peroxide oxidoreductase Registry number: EC 1.11.1.5 (12 Dec 1998) |
| cytochromes | Heme oxidation-reduction reactions such as photosynthesis and respiration. (09 Oct 1997) |
| cytochylema | The more fluid portion of the cytoplasm. Origin: cyto-+ G. Chylos, juice (05 Mar 2000) |
| cytocidal | Causing the death of cells. Origin: cyto-+ L. Caedo, to kill (05 Mar 2000) |
| cytocide | <pharmacology> Any chemical that kills or destroys living cells. (09 Oct 1997) |
| cytoclasis | Fragmentation of cells. Origin: cyto-+ G. Klasis, a breaking (05 Mar 2000) |
| cytoclastic | Relating to cytoclasis. (05 Mar 2000) |
| cytoclesis | The influence of one cell on another. Synonym: biotaxis, cytobiotaxis. Origin: cyto-+ G. Klesis, a call (05 Mar 2000) |
| cytocrine gland | A cell which secretes things that move directly from cell to cell. (09 Oct 1997) |
