[Cyanide-resistant respiration of Pseudomonas aeruginosa bacteria].
The transition of the bacterial culture into the stationary growth phase is accompanied by an appearance of cyanide-resistant respiration. Chloramphenicol inhibits the development of cyanide-resistant respiration. The cyanide-resistant oxidase is localized in the bacterial membrane. Its appearance is not due to the quantitative and qualitative changes of flavins, non-heme iron, ubiquinone and cytochromes of the b and c types, but is accompanied by an increase in the copper content of the membrane preparations. Neither cyanide-sensitive, nor cyanide-resistant chains of the bacterial electron transfer contain cytochromes of the a type. The cyanide-resistant oxidase accepts electrons at the ubiquinone--cytochrome b level of the main respiratory chain. The cyanide-resistant respiration is not accompanied by a formation of hydrogen peroxide. Cytochrome o performs the function of cyanide-sensitive oxidase. The nature of cyanide-resistant oxidase still remains obscure.
