Cytochrome c2

Gene

cycA

Organism
Rhodobacter capsulatus (strain ATCC BAA-309 / NBRC 16581 / SB1003)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Cytochrome c2 is found mainly in purple, non-sulfur, photosynthetic bacteria where it functions as the electron donor to the oxidized bacteriochlorophyll in the photophosphorylation pathway. However, it may also have a role in the respiratory chain and is found in some non-photosynthetic bacteria.
