Aeromonas sp. from Lamellidens marginalis produced L-asparaginase when grown at 37 degrees C. The optimum enzyme activity was at pH 9 when temperature was 45 degrees C. Half-life of partially purified enzyme at 50 degrees C and 55 degrees C was 35 and 20 min, respectively. Activation and deactivation energies of partially purified enzyme were 17.48 and 24.86 kcal mol-1 respectively. The enzyme exhibited a Km (L-asparagine) value of 4.9 x 10(-6) mol l-1 and a Vmax of 9.803 IU ml-1. Three metal… CONTINUE READING
