A new hydroxynitrile lyase (HNL) was isolated from the seed of Japanese apricot (Prunus mume). The enzyme has similar properties with HNL isolated from other Prunus species and is FAD containing enzyme. It accepts a large number of unnatural substrates (benzaldehyde and its variant) for the addition of HCN to produce the corresponding cyanohydrins in excellent optical and chemical yields. A new HPLC
从日本杏(Prunus mume)的种子中分离出一种新的羟腈裂解酶(HNL )。该酶与从其他李属物种中分离的HNL具有相似的特性,并且是含FAD的酶。它接受大量非天然底物(苯甲醛及其变体)以添加HCN,从而以优异的光学和化学收率生产相应的氰醇。针对该酶开发了一种新的基于HPLC的对映选择性测定技术,该技术可促进在缓冲溶液(pH = 4.5)中将KCN添加到苯甲醛中。
