Respiratory nitrate reductase: its localization in the cytoplasmic membrane of Klebsiella aerogenes and Bacillus licheniformis. 1979

F B Wientjes, and A H Kolk, and N Nanninga, and J Van T'Riet

The sidedness of the respiratory nitrate reductase in the cytoplasmic membrane of Bacillus licheniformis and Klebsiella aerogenes was studied by indirect immunofluorescence and by lactoperoxidase-catalyzed iodination. It was shown that the two subunits (Mr 150000 and 57000, respectively) of nitrate reductase of B. licheniformis are localized on the cytoplasmic side of the membrane, whereas the K. aerogenes enzyme is a transmembrane protein. The different localization of nitrate reductase in the membranes of these organisms may be related to their different rôle in oxidative phosphorylation.

UI	MeSH Term	Description	Entries
D007711	Klebsiella pneumoniae	Gram-negative, non-motile, capsulated, gas-producing rods found widely in nature and associated with urinary and respiratory infections in humans.	Bacillus pneumoniae,Bacterium pneumoniae crouposae,Hyalococcus pneumoniae,Klebsiella pneumoniae aerogenes,Klebsiella rhinoscleromatis
D009565	Nitrate Reductases	Oxidoreductases that are specific for the reduction of NITRATES.	Reductases, Nitrate
D002374	Catalase	An oxidoreductase that catalyzes the conversion of HYDROGEN PEROXIDE to water and oxygen. It is present in many animal cells. A deficiency of this enzyme results in ACATALASIA.	Catalase A,Catalase T,Manganese Catalase,Mn Catalase

D001407	Bacillus	A genus of BACILLACEAE that are spore-forming, rod-shaped cells. Most species are saprophytic soil forms with only a few species being pathogenic.	Bacillus bacterium
D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.	Species Specificities,Specificities, Species,Specificity, Species
D013104	Spheroplasts	Cells, usually bacteria or yeast, which have partially lost their cell wall, lost their characteristic shape and become round.	Spheroplast
