Catalase Activity in Leptospira.
Rao, P. J. (University of Illinois, Urbana), A. D. Larson, and C. D. Cox. Catalase activity in Leptospira. J. Bacteriol. 88:1045-1048. 1964.-A number of serotypes of Leptospira were found to possess catalase activity, although considerable variation in activity existed among various serotypes. Catalase activity of L. pomona was reduced by inhibitors commonly employed for arresting catalase acti...
متن کاملPhotometric determination of catalase activity.
Catalase activity may be measured quantitatively by the method of von Euler and Josephson (1) by allowing the enzyme solution to react with hydrogen peroxide for varying periods of time and measuring the excess peroxide remaining by titration with potassium permanganate. The similarity of this titration procedure to the assay of ascorbic acid by titration with 2:6-dichlorophenolindophenol sugge...
متن کاملCatalase Activity in Anaplasma Marginale.
Wallace, W. R. (Louisiana State University, Baton Rouge), and G. T. Dimopoullos. Catalase activity in Anaplasma marginale. J. Bacteriol. 91:309-311. 1965.-Extracts of erythrocytes infected with Anaplasma marginale were found to contain more catalase activity than normal erythrocytic preparations. The increase in catalase activity appeared concurrently with increases in the number of erythrocyte...
متن کاملThe activity of catalase in Pasteurella tularensis.
In an investigation (Sherstinsky, 1951; Yaniv, 1951) of the factors governing the virulence of Pasteurella tularensis (Bacterium tularense), the correlation between the activity of catalase and virulence was studied. This line of approach was suggested by the fact that in the Brucella group (Huddleson and Stahl, 1943) and in PasteureUa pestis (Rockenmacher, 1949) high virulence appears to be as...
متن کاملThe catalase activity of diiron adenine deaminase.
Adenine deaminase (ADE) from the amidohydrolase superfamily (AHS) of enzymes catalyzes the conversion of adenine to hypoxanthine and ammonia. Enzyme isolated from Escherichia coli was largely inactive toward the deamination of adenine. Molecular weight determinations by mass spectrometry provided evidence that multiple histidine and methionine residues were oxygenated. When iron was sequestered...
