Introduction
Cytochrome C is a small heme protein that plays a crucial role in the process of cellular respiration. It is located in the inner membrane of the mitochondrion and is involved in the electron transport chain. This protein has a unique structure that allows it to transfer electrons between enzymes and other molecules in the electron transport chain.
Cytochrome C Structure
The structure of cytochrome C is composed of a single polypeptide chain that folds into a compact globular shape. It has a molecular weight of approximately 12,000 daltons and contains a heme group that is covalently attached to the protein. The heme group is responsible for the protein's red color and its ability to transport electrons.
Cytochrome C Function
Cytochrome C plays a critical role in the electron transport chain by transferring electrons between molecules. It accepts electrons from complex III in the electron transport chain and donates them to complex IV. This transfer of electrons generates a proton gradient across the inner mitochondrial membrane that is used to produce ATP.
The Use of Cytochrome C in Research
Cytochrome C is also used extensively in research to study the evolutionary relationships between organisms. The amino acid sequence of cytochrome C is relatively conserved across different species, making it an ideal molecule for phylogenetic analysis.
