Notes:
Summary Experiments were carried out on the effects of some phenoxyacilic acids, used as herbicides, on the glutamic-dehydrogenase (GLDH) activity. 2,4-D,2,4,5-T, MCPA and Dichlorprop inhibited GLDH activity in a competitive way. Phenoxyacilic acids were ranked in the following order of affinity for the enzyme on the basis of the values of the inhibition constants: 2,4,5-T〉2,4-D〉MCPA〉Dichlorprop; on the basis of chemical structure, it was established that the carboxyl dissociation degree is instrumental in linking the herbicide with the active site of the enzyme.
