| Abstract: | Abstract Several heme aa 3-type cytochrome c oxidases, purified from the cytoplasmic membranes of bacteria, are able to catalyze the same reactions as the structurally far more complex eukaryotic enzyme, i.e., electron transport from cytochrome c to oxygen coupled to proton translocation. However, these oxidases show a very simple subunit pattern, and moreover, individual polypeptides even have homologous amino-acid sequences. This review summarizes the present data on purified bacterial cytochrome c oxidases and relates these findings to results obtained with the mitochondrial enzymes. |
