... using 1 unit NSP and 1 unit myrosinase. Chelators were added to a final concentration of 5m M. Activities of ESP and NSP are expressed as the amount of epithiopropyl cyanide (ESP) and benzyl cyanide ... ESP activity. In this series of assays, the formation of epith- ionitrile accounted for a maximum of 85% of the amount of total hydrolysis products. The results showed tha...
