Abstract
Positron annihilation studies have been carried out in two enzymes, lysozyme and catalase. Temperature dependence of the positron lifetimes in these two enzymes has been investigated. The results explained in terms of the free volume model and fluctuations between different conformational microstates of enzyme structures provide a new insight into the mechanism of bio-activity of these enzymes.
摘要
已对两种酶，即溶菌酶和过氧化氢酶进行了正电子湮没研究。研究了这两种酶中正电子寿命的温度依赖性。根据自由体积模型以及酶结构不同构象微态之间的涨落对结果进行的解释，为这些酶的生物活性机制提供了新的见解。
