Protein

Cytochrome c

Gene

cyc

Organism
Thunnus alalunga (Albacore) (Scomber alalunga)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Electron carrier protein. The oxidized form of the cytochrome c heme group can accept an electron from the heme group of the cytochrome c1 subunit of cytochrome reductase. Cytochrome c then transfers this electron to the cytochrome oxidase complex, the final protein carrier in the mitochondrial electron-transport chain.
