Simple peptides and their analogues having a primary amino group as the catalytic residue mediate the direct asymmetric intermolecular aldol reaction with high stereoselectivity and furnish the corresponding aldol products with up to 99% ee; this intrinsic ability of highly modular peptides may explain the initial molecular evolution of aldolase enzymes.
具有作为催化残基的主氨基的简单肽及其类似物,能以高立体选择性促进直接的不对称分子间醛醇反应,并生成最高达99% 对映体过量值的相应醛醇产物;这种高度模块化肽的内在能力可能解释了醛缩酶酶的初始分子进化过程。
