Names and origin

Protein names	Recommended name: Cytochrome c
Organism	Cannabis sativa (Hemp) (Marijuana)
Taxonomic identifier	3483 [NCBI]
Taxonomic lineage	cellular organisms › Eukaryota › Viridiplantae › Streptophyta › Streptophytina › Embryophyta › Tracheophyta › Euphyllophyta › Spermatophyta › Magnoliophyta › eudicotyledons › core eudicotyledons › rosids › fabids › Rosales › Cannabaceae › Cannabis

Protein attributes

Sequence length	111 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	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.
Subcellular location	Mitochondrion intermembrane space. Note: Loosely associated with the inner membrane.
Post-translational modification	Binds 1 heme group per subunit.
Sequence similarities	Belongs to the cytochrome c family.
