Urate oxidase in peroxisomes from maize root tips

  • Published:
Planta Aims and scope Submit manuscript

Summary

Peroxisomes isolated from maize root tips contained urate oxidase, although the supplementary enzymes allantoinase, allantoicase and NADH-glyoxylate reductase were not detected. Some glutamate-oxalacetate transaminase was present in peroxisomes. Enzymes of two other pathways occuring in plant peroxisomes, namely glycolate metabolism and the glyoxylate cycle, were not present. The root peroxisome thus resembles peroxisomes of the Arum spadix and supports the concept that peroxisomes constitute a dynamic and differentiating system.
