The natural occurrence of optically active isocitric acid was first demonstrated by Nelson' and Bruce(2) in blackberry fruits, and a somewhat large accumulation of the acid was found by Pucher et al. 3~ in Bryophyllum leaf tissue. This acid has also been recognized as a member of the tri-carboxylic acid cycle in many animals, plants and microorganisms. All isocitric acid, found before in nature...

3-Dehydroquinate synthase was purified to homogeneity from Escherichia coli. It was found to be a single polypeptide chain of M, = approximately 57,000. Reaction mixtures of pure enzyme and the substrate, 3deoxy-n-arabino-heptulosonic acid 7-phosphate, were incubated for short times and treated with NaB3H4. The resulting 3-deoxyheptonic acid 7-phosphate was degraded with sodium periodate, and f...
