- Activities are expressed as a percentage of the activity with the primary substrate for each enzyme. The activities of the control reaction were 50 nmol min−1 ml−1 for β-galactosidase I with β-ONPG as the substrate, 43 nmol min−1 ml−1 for β-galactosidase II with β-ONPG as the substrate, and 127 nmol min−1 ml−1 for α-galactosidase with α-PNPG as the substrate
