This article describes a simple method to determine the optimum pH for the activity of one enzyme in a coupled enzyme assay. Decoupling of the two-step reaction is achieved by heat denaturing the ...

The effect of pH on the production and specific activity of the extracellular proteinase enzymes of two ecologically distinct ericoid mycorrhizal fungi is described. The proteinase of Hymenoscyphus ...
