Cytochrome | Protein, Enzyme, Oxidase | Britannica
cytochrome, any of a group of hemoprotein cell components that, by readily undergoing reduction and oxidation (gain and loss of electrons) with the aid of enzymes, serve a vital function in the transfer of energy within cells.
Cytochrome - an overview | ScienceDirect Topics
Cytochrome c and c-type cytochromes occur in all eukaryotic organisms. The comparative analysis of the protein structures of cytochromes isolated from a multitude of different species of organisms has made it possible to establish evolutionary relationships between them.
Cytochrome - an overview | ScienceDirect Topics
Cytochromes consist of many families that have specific roles in respiration and photosynthesis. Cytochrome P450 or CYPs is a superfamily of hemeproteins that are typically the last of a set of oxidizing enzymes in electron transfer chains. By convention, specific enzymes in the system are referred to by CYP followed by a number such as CYP1A ...
Cytochromes - Examples, Definition, Types, Structure, Function
2024年6月28日 · Cytochrome c is a small, highly conserved protein that belongs to a class of proteins known as hemoproteins because it contains a heme group. This heme group holds an iron atom that plays a crucial role in electron transport within the cell.
Cytochrome - an overview | ScienceDirect Topics
A cytochrome is a protein that contains a heme group, which is a porphyrin with a central iron atom, allowing it to act as a single electron carrier. There are different classes of cytochromes (A-D) distinguished by their ability to absorb light at varying wavelengths.
The multiple functions of cytochrome c and their regulation in life …
Cytochrome c (Cytc) is essential in mitochondrial electron transport and intrinsic type II apoptosis. Mammalian Cytc also scavenges reactive oxygen species (ROS) under healthy conditions, produces ROS with the co-factor p66Shc, and oxidizes ...
Cytochromes - ScienceQuery
2023年2月15日 · About Cytochrome. C ytochromes are hemoproteins taking part in redox reactions by reversible transitions between the; Fe ++ and Fe +++ states. Cytochromes are members of electron transfer chains (respiratory chain, photosynthesis)and participate in enzymatic reactions (e.g. cytochrome P-450).
Cytochromes - SpringerLink
The term cytochrome was first coined by David Keilin to describe a set of intracellular heme-binding proteins that display redox activity with the formation of intense
Cytochrome c : functions beyond respiration - Nature
Cytochrome c is primarily known for its function in the mitochondria as a key participant in the life-supporting function of ATP synthesis.
Cytochrome C - Chemistry LibreTexts
Cytochrome c is an important component of the Electron Transport Chain for the synthesis of ATP (Figure 2). Cytochrome c is a water soluble electron transport protein that is loosely associated with the mitochondrial inner membrane.
