Abstract

The algae Mougeotia and Eremosphaera were used for isolation of microbodies with the characteristics of leaf peroxisomes and unspecialized peroxisomes, respectively. In both types of organelles, the following enzymes of the β-oxidation pathway were determined: acyl-CoA oxido-reductase, enoyl-CoA hydratase, and 3-hydroxyacyl-CoA dehydrogenase. There are indications that the peroxisomal oxidoreductase of both algae is a H2O2-forming oxidase rather than a dehydrogenase.

The enzymes enoyl-CoA hydratase and acyl-CoA oxidoreductase are located also in the mitochondria from Eremosphaera but not from Mougeotia. The mitochondrial acyl-CoA oxidizing enzyme was found to be a dehydrogenase. The specific activities of acyl-CoA oxidase and enoyl-CoA hydratase are lower than in spinach leaf peroxisomes. However, the activity of 3-hydroxyacyl-CoA dehydrogenase in the peroxisomes of both algae is almost 2-fold higher. The capability for degradation of fatty acids is a common feature of all different types of peroxisomes from algae.
