the reaction of n-ethylmaleimide with chorismate mutase/prephenate dehydratase ( chorismate pyruvatemutase/prephenate hydrolyase ( decarboxylating ) ec 5.4.99.5/ec 4.2.1.51 ) from escherichia coli k12 , which leads to the preferential inactivation of the prephenate dehydratase activity ( gething , m-j.h . and davidson , b.e . ( 1977 ) eur . j. biochem . 78 , 111-117 ) , was found to involve only the sulphydryl groups of the enzyme .
