title: [Role of CO-binding cytochrome c in enzymatic oxidation of methane by the bacterium Methylococcus capsulatus].
abstract: The cytochrome c spectrally related to cco cytochromes has been isolated and purified from the methane-oxidizing bacterium Methylococcus capsulatus. The cytochrome binds CO but does not bind other substrates of methane monooxygenase, does not activate the methane monooxygenase reaction and is not a component of methane monooxygenase. In the methanol dehydrogenase enzymatic system cytochrome cco functions as electron acceptor. A possible role of cytochrome cco as electron carrier intermediate in the sequence of the dehydrogenase and oxidase enzymatic systems of M. capsulatus is discussed.
