Cloning of the cyo locus encoding the cytochrome o terminal oxidase complex of Escherichia coli.

PMCID: PMC212375  PMID: 3036778

Abstract

The structural genes encoding the cytochrome o terminal oxidase complex (cyo) of Escherichia coli have been subcloned into the multicopy plasmid pBR322 after the Mu-mediated transposition of the gene locus from the bacterial chromosome onto the conjugative R plasmid RP4. Introduction of cyo plasmids into strains (cyo cyd) lacking both terminal oxidases restored the ability of the strains to grow aerobically on nonfermentable substrates. Strains carrying the cyo plasmids produced 5 to 10 times more cytochrome o oxidase than did control strains. The gene products encoded by the cyo plasmids could be immunoprecipitated with monospecific antibodies raised against cytochrome o. The cloned genes will be valuable for studying the structure, function, and regulation of the cytochrome o terminal oxidase complex.
