摘要：

酶在生物体内以及工业应用里有着极其关键的作用，凭借其独特的催化性能，成为催化剂的关键选择之一。然而传统的酶改造与设计方法面临不少挑战，如序列空间庞大以及多目标优化存在困难等情况。近年来，人工智能（artificial intelligence, AI）技术中的深度学习和生成式人工智能方法，为酶改造与设计提供了新思路和解决方案，可在大规模数据的支撑下突破这些限制。AI驱动的策略实现了高效的序列空间探索和精准的结构-功能关系预测，并借助强化学习框架协调多目标优化。这些方法不仅显著加速了酶的工程化进程，更在提升催化效率、增强热稳定性、改善底物选择性等方面取得了突破性成果。本文系统综述了人工智能驱动酶改造与设计的最新研究进展，从基础数据库构建、智能改造策略、智能设计方法等方面进行了深入分析，同时探讨了当前面临的数据、模型及工程化挑战与未来发展方向。这些创新为设计高性能、多功能的酶开辟了广阔道路，并将推动生物制造、环境修复和生物育种等领域向更高效、智能和可持续的方向发展。

Abstract:

Enzymes play a crucial role in both biological systems and industrial applications. Due to their unique catalytic properties, they are among the key choices for catalytic processes. However, traditional enzyme engineering and design approaches face significant challenges, such as the vastness of sequence space and the complexities associated with multi-objective optimization. In recent years, artificial intelligence (AI) technologies, particularly deep learning and generative AI methods, have provided novel perspectives and solutions for enzyme modification and design, enabling breakthroughs in overcoming these limitations with large-scale data support. AI-driven strategies have facilitated efficient exploration of sequence space, accurate prediction of structure-function relationships, and the coordinated multi-objective optimization using reinforcement learning frameworks. These methods have not only significantly accelerated the enzyme engineering process but also led to groundbreaking advancements in the enhancement of catalytic efficiency, thermal stability, and substrate specificity. This review systematically summarizes the latest research on AI-driven enzyme modification and design, providing an in-depth analysis of foundational database construction, intelligent modification strategies, and design methodologies. Furthermore, it discusses current challenges related to data, models, and engineering applications, as well as future directions. These innovations open up vast possibilities for the design of high-performance, multifunctional enzymes and are poised to propel fields such as biomanufacturing, environmental remediation, and agricultural biotechnology toward more efficient, intelligent, and sustainable development.
