Abstract
Euglena gracilis was found to contain a peroxidase that specifically require L-ascorbic acid as the natural electron donor in the cytosol. The presence of an oxidation-reduction system metabolizing L-ascorbic acid was demonstrated in Euglena cells. Oxidation of L-ascorbic acid by the peroxidase, and the absence of ascorbic acid oxidase activity, suggests that the system functions to remove H2O2 in E. gracilis, which lacks catalase.This publication has 30 references indexed in Scilit:
