The stability of invertase was studied under various conditions, including at 75 degrees C, in presence of stabilizers (sorbitol and glycerol) at 75 degrees C, and in the presence of denaturants (urea and trichloroacetic acid) at 37 degrees C in reverse micelles. Stability of the invertase in reverse micelles was found to be improved over that of the enzyme in bulk aqueous solution. Sorbitol could enhance enzyme stability as it does in the bulk aqueous system. The stabilizing effect of glycerol was reduced in reverse micelles. The denaturation pattern of urea remains unaltered. However, the denaturation effect of trichloroacetic acid has been reduced in reverse micelles.
在各种条件下研究了转化酶的稳定性,包括在75摄氏度、75摄氏度下存在稳定剂(山梨醇和甘油)以及在37摄氏度下反胶束中存在变性剂(尿素和三氯乙酸)的情况下。发现转化酶在反胶束中的稳定性比在本体水溶液中的酶稳定性有所提高。山梨醇能像在本体水体系中一样增强酶的稳定性。甘油在反胶束中的稳定作用降低。尿素的变性模式保持不变。然而,三氯乙酸在反胶束中的变性作用已降低。
