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...

Studies on Plant Hypertensinase
Many plants contain an enzyme similar in most biological properties to the hypertensinase obtained from blood and some animal tissues, notably kidney and intestinal mucosa. Wheat bran is a rich source of the plant hypertensinase, and from it a potent, non-toxic preparation was made by the use of isoelectric and ammonium sulfate precipitation as the means of purification. Hypertensinase derived ...
متن کاملStudies on catalase inhibition as related to tumors.
The inhibition of catalase in vitro by boiled extracts of tumors has been recently demonstrated (1). It was also found that fresh liver and spleen contained small amounts of a factor having similar action. In further work it was found that autolyzed liver homogenates contained large amounts of such inhibitory material. Studies on the rate of formation in liver homogenates, attempts at purificat...
متن کاملStudies on Isolated Plant Protoplasts
Isolated tomato fruit protoplasts have been observed to take up both tobacco mosaic virus and ferritin by the process of pinocytosis. These studies have involved electron microscopic observations on thin sections of suitably fixed and embedded material. These electron microscopic studies have also shown that very close association exists between the nucleus and chloroplasts in these proto plas...
