abstract: In the extracts of Quercus pedunculata roots, the activities of 5-dehydroquinate hydro-lyase and shikimate: NADP oxydoreductase are eluted in the same fractions whatever separation procedures are used: chromatography on Sephadex G 100, DEAE cellulose and hydroxylapatite, centrifugation in sucrose density gradient, disc electrophoresis. These results are closely related to those obtained on the aggregate of enzymes involved in the shikimate pathway in Neurospora crassa. The molecular weight of the association determined by gel filtration is about 55,000.
