Redox reactions play important roles in almost all biological processes, including
photosynthesis and respiration, which are two essential energy processes that sustain all life …

It has been estimated that about 90% of the reduction of molecular oxygen in the biosphere
is catalyzed by respiratory oxidases (95). Much of this is accomplished by a wide variety of …

This article tries to be a compact summary of some recent research on cytochrome c oxidase
(EC 1.9. 3.1), an important enzyme in membrane bioenergetics. Cytochrome oxidase is the …

The cytochrome o complex is one of two ubiquinol oxidases in the aerobic respiratory
system of Escherichia coli. This enzyme catalyzes the two-electron oxidation of ubiquinol-8 …

Ithas been estimated that nearly 90% of the 02 consumed by aerobic organisms participates
in the dioxygen chemistry of cytochrome c oxidase and becomes reduced to water in the …

The structural genes of cytochrome‐c oxidase in Bacillus subtilis have been isolated and
sequenced. Five genes, ctaB–F, are closely spaced. ctaC, ctaD, ctaE and ctaF are the genes …

Revised Manuscript Received December 27, 1994® abstract: The ubiquinol oxidase,
cytochromeboi, of Escherichia coli is a member of the respiratory heme—copper oxidase …

Further genetic evidence is provided here that Bradyrhizobium japonieum possesses a
mitochondria‐like electron‐transport pathway: 2 [H]→ UQ→ bc1→ c→ aa3→ O2. Two Tn5 …

Cytochrome aa3 is one of two terminal oxidase complexes in the Bacillus subtilis electron
transport chain. A novel genetic strategy was devised which permitted the isolation of B …

The gene coding for four subunits of cytochrome aa3-type oxidase was isolated from a
genomic DNA library of the thermophilic bacterium PS3 and sequenced. The N-terminus of …
