Figure 3From: A new chymotrypsin-like serine protease involved in dietary protein digestion in a primitive animal, Scorpio maurus: purification and biochemical characterizationEffects of temperature. (A) Effects of temperature on SCP and BCP activities. (B) Effects of temperature on SCP and BCP stabilities. Enzyme activity was tested at various temperatures using casein as substrate at pH 9 for the SCP and at pH 7.5 for the BCP in the presence of 4 mM CaCl2. Residual enzyme activity was determined after 15 min in incubation and the initial activity before incubation was taken as 100%.Back to article page
