Function

[CYB_RHOCA] 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 (By similarity). [UCRI_RHOCA] 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. [CY1_RHOCA] 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.

Publication Abstract from PubMed

Ubihydroquinone: cytochrome (cyt)c oxidoreductase, or cyt bc (1), is a widespread, membrane integral enzyme that plays a crucial role during photosynthesis and respiration. It is one of the major contributors of the electrochemical proton gradient, which is subsequently used for ATP synthesis. The simplest form of the cyt bc (1) is found in bacteria, and it contains only the three ubiquitously conserved catalytic subunits: the Fe-S protein, cyt b and cyt c (1). Here we present a preliminary X-ray structure of Rhodobacter capsulatus cyt bc (1) at 3.8 A and compare it to the available structures of its homologues from mitochondria and chloroplast. Using the bacterial enzyme structure, we highlight the structural similarities and differences that are found among the three catalytic subunits between the members of this family of enzymes. In addition, we discuss the locations of currently known critical mutations, and their implications in terms of the cyt bc (1) catalysis.
