目前，酶的再设计都集中在改变酶分子的底物或辅因子的专一性及反应的立体专一性，而鲜有改变反应的化学专一性的报道。

So far , all the examples of enzyme redesign have focused on changing substrate or cofactor specificity or altering the stereochemistry of a reaction , but no body has demonstrated alteration of reaction chemistry .

原子经济性，作为衡量合成方法效能的新标准是重要的，但经济性的考虑必须建立在立体化学选择性/专一性的基础上，这表明化学专一性是更基本的，因而是更重要的。

Atom economy is important as a new standard to measure the quality of a synthetic method , however , the economic consideration has to be taken on the basis of stereochemical selectivity / specificity . This fact indicates that chemical specificity is more fundamental and important .
