The role of an extra fragment of cytochrome b (residues 309-326) in the cytochrome bc1 complex from Rhodobacter sphaeroides.

Biochemistry - 19 Sept 2006

Gong Xing, Yu Linda, Yu Chang-An

Abstract excerpt

In bacterial cytochrome b of the cytochrome bc(1) complex, there is an extra fragment located between the amphipathic helix ef and the transmembrane helix F compared to the mitochondrial counterparts. In this work, mutants at various positions of this extra fragment were generated in Rhodobacter sphaeroides in an effort to investigate its specific role in the bacterial bc(1) complex. The total deletion...
