A cDNA clone encoding a rice catalase isozyme.
Catalase (H202: H202 oxidoreductase, EC 1.11.1.6) is a heme-containing enzyme that converts H202 into oxygen and water. In plants, catalase is involved in scavenging H202, which is generated during the course of photorespiration and P-oxidation of fatty acids. It also plays an important role in detoxification of active oxygen species that are generated by various environmental stresses (Scandal...
متن کاملIsozyme Polymorphisms in Daphnia
Temporal sequences of allele frequencies in natural populations of Daphnia are analyzed to obtain the mean and variance of the selection coefficient for both asexual and sexual phases. In general, the alleles at enzyme loci appear to be quasi-neutral. Although significant variation exists for the estimated selection coefficients, the means are in all cases close to zero. Estimates of the varian...
متن کاملEsterase Isozyme of Diamondback Moth
Electrophoresis is currently the best technique for quantifying inherited variation which has contributed to our knowledge of population biology in revealing population structure. Considerable variation in isozymes of diamondback moth, Plutella xylostella (L.), was detected. Esterase zymograms were prepared from 3rd and 4th instar larvae, pupae and adults. There were two groups of esterase band...
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 کاملSpectroscopy of Catalase
Catalase is resistant to oxidizing agents; e.g., ferricyanide. It is also resistant to reducing agents; e.g., catalytically activated hydrogen, hydrosulfite, ferrotartrate, cysteine. The hemin group of the enzyme will combine with cyanide, sulfides, nitric oxide, fluoride. It will not combine with carbon monoxide. Catalase is therefore a ferric complex. The stability of the ferric iron in the e...
