Protein

Cytochrome c1

Gene

petC

Organism
Rhodobacter capsulatus (Rhodopseudomonas capsulata)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is a respiratory chain that generates an electrochemical potential coupled to ATP synthesis. c1 functions as an electron donor to cytochrome c.

Caution

The sequence reported in PubMed:3004982 was thought to originate from R.sphaeroides but was later shown to be derived from R.capsulatus.1 Publication
