Staphylococcus aureus, cytochromes

The entries in Table XX are only an experimentally studied subset of all the cytochromes c that exist a complete compilation would very nearly require a minimum of one entry per organism using electron transport in its metabolism. Physiological studies on representative microorganisms throughout the spectrum of bacteria make it safe to generalize that c-type cytochromes occur hand in hand with electron transport chains. The apparent exceptions such as Staphylococcus aureus, which contains only h-, o-, and a-type cytochromes (359), are most likely para-...

Mitochondria and unicellular organisms. Bacteria have no mitochondria. Being of mitochondrial size, the bacterium has to function as its own mitochondrion its plasma membrane, although it lacks aristae, has to attempt to carry out as many as it can of the complex activities of eukaryotic mitochondria. Hence many of the typical enzymes of eukaryotic mitochondria are located in the bacterial plasma membrane (De Ley and Docky, i960 Mitchell and Moyle, 1956a). In particular, the enzymes of the tricarboxylic acid cycle are found there. More than 90% of the cell s succinic, malic, lactic, and formic dehydrogenases, as well as the cytochrome oxidase, are present in the plasma membrane of typical bacteria, e.g. Staphylococcus aureus and Micrococcus lysodeikticus (Mitchell, 1961,1963).
