Epoxide hydrolase plays a minor role because a strong epoxide hydrolase inhibitor 3 3 3-trichloropropene oxide showed a weak inhibitory effect on the p-nitrophenol formation The epoxy intermediate is so labile that the hydrolysis of the epoxide proceeds mostly nonenzymically even at a neutral pH Induction experiments suggested that NPVE was susceptible to a wide varieties of
