The enzymatic hydrolyses of a variety of α-substituted mandelic and lactic esters using pig liver esterase (PLE) have been investigated. High to moderate enantioselectivity was found for various α-substituted mandelic esters, whereas PLE showed low to no enantioselectivity for α-substituted lactic esters. We observed that the enantioselectivity of PLE depends strongly on the length and nature of the
已经研究了使用猪肝酯酶(PLE)酶促水解各种α-取代的扁桃酸酯和乳酸酯的方法。发现对各种α-取代的扁桃酸酯具有高到中等的对映选择性,而PLE对α-取代的乳酸酯显示出低至没有对映选择性。我们观察到,PLE的对映选择性很大程度上取决于α位置取代基的长度和性质。讨论了PLE的活动站点模型的一些后果。
