摘要

研究了稀水溶液中过氧化氢酶的辐射失活，给出了过氧化氢酶生物活性与吸收剂量的关系以及辐射气氛、温度和溶液中酶的初始浓度对酶活性的影响。结果表明，低温、较高的酶初始浓度和体系中的氧对过氧化氢酶的辐射失活有不同程度的抑制作用。发现添加剂CH,3,CH,2,OH、HCOONa和EDTA对稀水溶液中过氧化氢酶的辐射失活有明显的保护作用。同时讨论了失活机理和添加剂保护机理。

Abstract

In this work the radiationin-dnced deactivation of catalase in dilute aqueous solution was reported. The effects of irradiation atmosphere, temperature and original concentration of catalase, in dilute aqueous solutions on the deactivation of catalase were investigated. The protective effect by some additives (CH,3,CH,2,OH, HCOONa and EDTA) to radiation deactivation in dilute aqueous solutions was also studied. Remarkable protective effect by those additives was observed. The mechanism of radiation deactivation and protective effect have been discussed.
