title: Assay of enzyme effectors.
abstract: The effects of various classes of organic compounds and of metal ions on the catalytic activity of horseradish peroxidase in hydrogen peroxide-catalysed o-dianisidine oxidation and, on the activity of alkaline phosphatase in p-nitrophenyl phosphate hydrolysis have been studied. Enzymic methods have been developed for determination of sulphur compounds at 10(-5)-10(-4)M, nitrogen compounds at 2 x 10(-7)-3 x 10(-5)M mercury at 3 x 10(-7) mu/ml and lead at 6 x 10(-4) mu/ml concentration.
