红心萝卜黑芥子酶的性质及热变性动力学研究
Study on properties and thermodynamics of myrosinase from red radish
摘要
Abstract
The effect of pH,temperature and Vitamin C on myrosinase from red radish were studied and the optimum pH and temperature were 5.4 and 22℃,respectively.And the myrosinase activity improved 2.6 folds when the concentration of Vitamin C reached 1.60mmol/L.At 90℃ and 100℃,the kinetics curve of myrosinase activity fitted a first-order reaction by the linear regression analysis,and the estimated kinetics parameters of k-value were 9.93×10-2 and 15.43×10-2min-1,respectively,corresponding to the half-lives of 6.98min and 4.49min.关键词
