酶学上重要的构象变化已经根据触发物的性质(大写S, I, A表示底物,反应中间体,变构改性剂)和变化速率(下标S表示相对于酶反应快或慢)进行了分类。这表明,在Cu超氧化物歧化酶中,已知产物在非平衡条件下的质子化(生成H2O2)涉及本质上不可逆的if变化。
Enzymatically important conformation changes have been classified according to the nature of the trigger (capital S, I, A for substrate, reaction intermediate, allosteric modifier) and the rate of change (subscript f or s, if fast or slow relative to the enzymatic reaction). It is suggested that, in Cu Superoxide dismutase, the known protonation of the product (to give H2O2) under nonequilibnum conditions involves an essentially irreversible Ifchange.
