STUDIES ON THE CATALASE I. BEHAVIOR OF CATALASE IN THERMOPHILIC CELLULOSE FERMENTER

The Magnetic Behavior of Catalase

The magnetic moment of catalase is 4.6 +/- 0.3, nearly the same as that of ferric hemoglobin hydroxide. If the moment be due to electron spin alone without orbital contribution, 3 free electrons would give rise to 3.9 magnetons.

Studies on the Effect of Temperature on the Catalase Reaction. Ii. Loss of Catalase Activity

In the preceding paper (1) the possibility of spontaneous inactivation of the enzyme by heat has been mentioned as a factor responsible for the diminished catalase activity, especially at temperatures above 20°C. To determine to what extent this may have played a r61e in the experiments at different temperatures, the activity of catalase subjected for various lengths of time to the influence of...

Is Root Catalase a Bifunctional Catalase-Peroxidase?

Plant catalases exhibit spatial and temporal distribution of their activity. Moreover, except from the typical monofunctional catalase, a bifunctional catalase-peroxidase has been reported. The aim of this study was to investigate whether the leaf and root catalases from six different plant species (Lactuca sativa, Cichorium endivia, Apium graveolens, Petroselinum crispum, Lycopersicon esculent...
