Glycoside Hydrolase Activities in Cell Walls of Sclerenchyma Cells
... Therefore, five different pH values, between pH 5.0 and pH 7.0, were tested for each substrate (Table 1). The highest signal was typically observed when the pH was slightly acidic (6.0–6.5), likely reflecting a compromise between resorufin ionization and enzyme activity, with the exception of Glc-S- ...
