蛋白质是生命体的重要组成部分,其中生物酶在生命体系中发挥至关重要的作用。蛋白质分子设计是研究生物酶结构与功能关系的重要手段。本文综述了基于蛋白质骨架的人工水解酶的理性设计与功能研究进展,包括对天然蛋白的重新利用和重新改造,基于3-股螺旋、4-股螺旋或锌指蛋白的分子设计,以及血红蛋白（如细胞色素b5和肌红蛋白突变体）水解酶催化活性的调控等,阐明了人工水解酶分子设计的基本思路与研究方法,为合理构建人工水解酶或其他生物酶提供了重要的信息。人工水解酶的理性设计进展,不但深化我们对天然酶结构-性质-反应-功能关系的认识,而且还提升我们创造具有优越功能的人工生物酶的能力。

Proteins are an important part of life, of which enzymes perform vital roles in biological systems. Rational protein design is a key approach for investigating the structure and function relationship of enzymes. This review summarizes the progresses in rational design and functional study of artificial hydrolases in protein scaffolds, including reuse of natural proteins, reconstruction of natural proteins, molecular design based on 3-α-helix, 4-α-helix or zinc-finger proteins, and fine-tuning the hydrolysis activity of heme proteins such as c...
