catalysis declines due to suicide inactivation; catalysis declines due to suicide inactivation. Following column chromatography, e.g. ion exchange or zinc-affinity chromatography, hydroperoxide isomerase activity is often decreased and sometimes even undetectable by TLC, whereas 8-dioxygenase activity is always present. However, storage of the enzyme for a few days on ice often restores the hydroperoxide isomerase and appeares to increase the 7,8-linoleate diol synthase activity as well |
