with the most preferred substrate petiveriin, Petiveria alliacea alliinase shows 80% higher activity at 37°C and 100% higher activity at 52°C than at ambient temperature (25°C). Even at 67°C, alliinase activity is still 19% higher than that observed at room temperature, indicating that the alliinase retains significant functionality over a broad range of temperature and possesses a high overall intrinsic thermal stability
