O que (quem) é cytochrome - definição

REDOX ACTIVE PROTEINS CONTAINING A HEME WITH A FE ATOM AS A COFACTOR

Cytochromes; Cytochrome a; Cytochrome c6f complex

cytochrome

¦ noun Biochemistry any of a number of compounds consisting of haem bonded to a protein, involved in cellular respiration.

Cytochrome b

GROUP OF MITOCHONDRIAL PROTEINS INVOLVED IN THE RESPIRATORY CHAIN

Cyt b; Cytochrome B; Cytochrome-b; Cytochrome b6; Mitochondrial cytochrome b; Cyt-b; F129L; G143A

Cytochrome b within both molecular and cell biology, is a protein found in the mitochondria of eukaryotic cells. It functions as part of the electron transport chain and is the main subunit of transmembrane cytochrome bc1 and b6f complexes.

Cytochrome P450

SUPERFAMILY OF ENZYMES CONTAINING HEME AS A COFACTOR THAT FUNCTION AS MONOOXYGENASES

Cytochrome p450; Cytochrome P450 monooxygenase system; P450; Cytochrome P450 monooxygenase; Cyp450; Cytochrome p-450 enzyme system; Cyt P450; Cytochrome P-450; Cytochrome P450 oxidase; Cytochrome 450; CYP450; Cyp family; Cytochrome P450 enzyme system; P450 oxidase; Cytochrome P450 system; Cytochrome P450 family; CYP 450; P450 system; CYP2D1; P-450; Compound I; Compound II; Compound-I; Compound-II; CYP2C; CYP1; CYP2; CYP3; CYP4; CYP5; CYP7; CYP8; CYP20; CYP27; Cytochrome P450s; CYP337B3; Cytochrome-P450; P450 monooxygenase

Cytochromes P450 (CYPs) are a superfamily of enzymes containing heme as a cofactor that functions as monooxygenases. In mammals, these proteins oxidize steroids, fatty acids, and xenobiotics, and are important for the clearance of various compounds, as well as for hormone synthesis and breakdown.

Cytochrome

Cytochromes are redox-active proteins containing a heme, with a central iron (Fe) atom at its core, as a cofactor. They are involved in electron transport chain and redox catalysis. They are classified according to the type of heme and its mode of binding. Four varieties are recognized by the International Union of Biochemistry and Molecular Biology (IUBMB), cytochromes a, cytochromes b, cytochromes c and cytochrome d.

Cytochrome function is linked to the reversible redox change from ferrous (Fe(II)) to the ferric (Fe(III)) oxidation state of the iron found in the heme core. In addition to the classification by the IUBMB into four cytochrome classes, several additional classifications such as cytochrome o and cytochrome P450 can be found in biochemical literature.
