Abstract

SUMMARY: Glucose-6-phosphate isomerase was partially purified from cells of in the culmination stage of development. The enzyme had a pH optimum of about 8·5 in Tris/HCl buffer. Activity was not inhibited by -chloromercuribenzoate or iodoacetate. The enzyme exhibited Michaelis–Menten kinetics and the values for glucose 6-phosphate and fructose 6-phosphate were 2 mm and 0·1 mm, respectively. Erythrose 4-phosphate was a strong competitive inhibitor of the enzyme with a value of 3·8 μm, whereas 6-phospho-gluconate was less effective with a of 0·1 mm.
