Allantoic Acid Synthesis in Soybean Root Nodule Cytosol via Xanthine Dehydrogenase.

abstract：:beta-Glucan synthetase activity in growing regions of pea (Pisum sativum L.) epicotyls was assayed by supplying UDP-glucose to particulate fractions of tissue homogenates or to thin tissue slices. Particulate fractions are less active in forming alkali-insoluble glucan than slices from the same tissue, although many k...
