Protein

Cytochrome b6-f complex iron-sulfur subunit

Gene
petC, CT0302
Organism
Chlorobium tepidum (strain ATCC 49652 / DSM 12025 / TLS)
Status
Reviewed - Annotation score: 4 out of 5 - Protein inferred from homologyi

Functioni

Component of the green S-bacteria bc-complex which consists of the Rieske protein and cytochrome b subunit and which appears to lack a cytochrome c1-equivalent. This complex has a comparatively low redox potential.

Catalytic activityi

Plastoquinol + 2 oxidized plastocyanin + 2 H+(Side 1) = plastoquinone + 2 reduced plastocyanin + 4 H+(Side 2).

Cofactori

Binds 1 2Fe-2S cluster per subunit By similarity.
