focusing on (i) the reaction stereocontrol, (ii) the possibility of combining it with other mesophilic enzymes in multienzyme systems and (iii) its application to the synthesis of imino‐ and nitrocyclitols. In our study, the diastereoselectivity of Rhu1PATm was similar to the one reported for Rhu1PA from Escherichia coli (Rhu1PAEc). However, we observed significant differences for some aldehyde acceptors
最近已经克隆和鉴定了来自滨海嗜热菌的鼠李糖1-磷酸醛缩酶(Rhu1PA Tm)。这种超嗜热酶为实际催化提供了有趣的可能性。这是由于其在极端反应条件下(例如高温或存在有机助溶剂)的高稳定性。已探索了Rhu1PA Tm在有机合成中的潜力,重点在于(i)反应立体控制,(ii)在多酶系统中将其与其他嗜温酶结合的可能性,以及(iii)在亚氨基和硝基环醇合成中的应用。在我们的研究中,Rhu1PA Tm的非对映选择性类似于报道的大肠杆菌Rhu1PA的非对映选择性。(Rhu1PA Ec)。但是,我们观察到某些醛受体的显着差异。的确,非对映选择性控制不完全,因为混合物大号-苏式(2 - [R,3小号;天然stereopreference)和d -赤(2 - [R,3 - [R作为Rhu1PA描述得到)对映异构体的Ec。Rhu1PA Tm能够使用硝基醛和N -Cbz-氨基醛催化醛醇缩合反应。所选nitroal
