Cloned (Comment) Organism
Production of cytochrome c oxidase deficient strains and ANR deficient strain. Pseudomonas putida

Inhibitors

Inhibitors Comment Organism Structure
KCN 1 mM inhibits all terminal oxidases excepting the CIO quinol oxidase and lead to reduced NADH oxidation between 2.5- and 4fold Pseudomonas putida
additional information Inactivation of the Aa3 oxidase lead to a 50% reduction in N,N,N',N'-tetramethyl-1,4-benzenediamine (TMPD)-dependent oxidase activity (electron donor specific for cytochrome c-dependent oxidases). Lack of the Cbb3-2 oxidase lead to 65% reduction.; In cells growing exponentially under high oxygen tension (100% air saturation), the absence of ANR lead to a 20fold decrease in mRNA levels of the Cbb3-1 oxidase gene, a decrease that is 10-fold lower than that observed in cells growing exponentially in shaken flasks, and 35-fold lower than in cells entering the stationary phase. When cells are grown under limiting oxygen supply (40% air saturation), the absence of ANR lead to a over 500fold decrease in the mRNA levels of the Cbb3-1 oxidase gene; Under aerobic conditions, inactivation of transcriptional activator gene ANR lead to a significant decrease (more than 230fold) of the mRNA corresponding to the Cbb3-1 oxidase, but have little effect on the other analysed terminal oxidases Cbb3-2 and Aa3.
