In vitro reconstitution of electron transport from glucose-6-phosphate and NADPH to nitrite

abstract：:Allantoin and allantoic acid are the major forms of nitrogen transported from soybean nodules to other parts of the plant. Neither the pathway or the site of ureide synthesis has been demonstrated in root nodules.Bacteroid and cytosol (plant portion) fractions were prepared and the purity of each fraction was determin...
