Resistant Photosynthesis and Enhanced Catalase Activity
Experiments are described further indicating that 02-resistant photosynthesis observed in a tobacco (Nicotiana tabacum) mutant with enhanced catalase activity is associated with decreased photorespiration under conditions of high photorespiration relative to net photosynthesis. The effects on net photosynthesis of (a) increasing O2 concentrations from 1% to 42% at low CO2 (250 microliters CO2 p...
متن کاملIs 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...
متن کاملCatalase Concentration
Brahn (3) observed very low liver catalase ac tivity in human beings who had died as the result of malignant growths. Later work showed that of all the individual liver enzymes studied in can cerous rats and mice the activity of catalase was by far the most affected. Greenstein and co workers (6, 7) have reported that with the pro gressive growth of the tumor there is a decrease in liver catala...
متن کاملEffects of inhibitors of catalase on photosynthesis and on catalase activity in unwashed preparations of intact chloroplasts.
The catalase activity of unwashed preparations containing intact spinach (Spinacia oleracea L.) chloroplasts is inhibited both by cyanide and by azide at concentrations which also cause inhibition of photosynthetic CO(2)- dependent O(2) evolution.Aminotriazole can also be used to inhibit this contaminant catalase, and in this case inhibition of catalase can be achieved at aminotriazole concentr...
متن کاملCatalase 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...
