Electron transfer processes in subunit I mutants of cytochrome bo quinol oxidase in Escherichia coli.

Bioscience, biotechnology, and biochemistry - 1 Jul 2009

Kobayashi Kazuo, Tagawa Seiichi, Mogi Tatsushi

Abstract excerpt

Cytochrome bo is a terminal quinol oxidase in the aerobic respiratory chain of Escherichia coli. Subunit I binds all four redox centers, and electrons are transferred from quinols to high-spin heme o and Cu(B) through a bound uniquinone-8 and low-spin heme b. To explore the role of conserved charged amino acid residues, we examined the one-electron transfer processes in subunit I mutants. We found that all the...
