Proton pumping heme‐copper oxidases represent the terminal, energy‐transfer enzymes of respiratory chains in prokaryotes and eukaryotes. The CuB‐heme a3 (or heme o) binuclear center, associated with the largest subunit I of cytochrome c and quinol oxidases, is directly involved in the coupling between dioxygen reduction and proton pumping. The role of the other subunits is less clear. The following aspects will be covered in this paper:i) the efficiency of coupling in the mitochondrial aa3… 

Mechanism of Proton-Motive Activity of Heme-Copper Oxidases

Recent ideas are reviewed on some of the critical features that likely underlie the mechanism of coupling of proton and electron transfers and to relate them to the available structural information.

Probing a Role of Subunit IV of the Escherichia coli bo-type Ubiquinol Oxidase by Deletion and Cross-linking Analyses*

It is proposed that subunit IV is present in a cleft formed by subunits I and III and assists the CuB binding to subunit I during biosynthesis or assembly of the oxidase complex.

Proton Pumps of Respiratory Chain Enzymes

Proticity is essentially used to drive phosphorylation of ADP to ATP by the FOF1-ATP synthase of coupling membranes and can drive solute transport by proton coupled transporters and mechanical work as in bacterial flagella, and can result in heat production in brown adipose tissue mitochondria.

Following nearly eight years of controversy, after Wikstrirm began in 1977 to cite evidence in favor of a redox-linked proton-pumping function in cytochrome oxidase, it has become widely agreed that cyto chrome oxidase is protonmotive as well as electronmotive.

Results are presented which suggest a general mechanism for the entry and binding of exogenous ligands at the “binuclear site” (CuB Fea3) of the heme-copper oxidases and it is suggested that these ligand shuttle reactions might be functionally important in providing a coupling mechanism for electron transfer and proton translocation.

Insight into the active-site structure and function of cytochrome oxidase by analysis of site-directed mutants of bacterial cytochromeaa3 and cytochromebo

A summary of site-directed mutants of conserved residues in these two enzymes is presented and discussed in terms of a current model of the structure of the metal centers and evidence for regions of the protein likely to be involved in proton transfer.

Oxygen activation and the conservation of energy in cell respiration

The molecular mechanism of 02 reduction and its linkage to H+ translocation are now emerging and the bimetallic haem iron–copper reaction centre in this family of enzymes is the critical structure for catalysis of both these processes.
