¹Plant-derived protease from the fruits of Solanum elaeagnifolium. MCA=milk-clotting activity expressed in soxhlet units per milliliter (SU mL^-1). Sp-MCA=specific milk-clotting activity expressed in soxhlet units per milligram of enzyme (SU mg^-1). PA=proteolytic activity expressed in tyrosine units per milliliter (U_Tyr mL^-1). Sp-PA=specific proteolytic activity expressed in tyrosin units per milligram of enzyme (U_Tyr mg^-1). ^a,b,cMean values in the same row with different superscripts differ (ANOVA, Tukey-Kramer test, ). Data represent the average of three replicates ().
