Lipases are remarkable biocatalysts, adept at catalyzing the breakdown of diverse compounds into glycerol, fatty acids, and mono- and di-glycerides via hydrolysis. Beyond this, they facilitate esterification, transesterification, alcoholysis, acidolysis, and more, making them versatile in industrial applications. In industrial processes, lipases that exhibit high stability are favored as they can withstand harsh conditions. However, most native lipases are unable to endure adverse conditions, making them unsuitable for industrial use. Protein engineering proves to be a potent technology in the development of lipases that can function effectively under challenging conditions and fulfill criteria for various industrial processes. This review concentrated on new trends in protein engineering to enhance the diversity of lipase genes and employed in silico methods for predicting and comprehensively analyzing target mutations in lipases. Additionally, key molecular factors associated with industrial characteristics of lipases, including thermostability, solvent tolerance, catalytic activity, and substrate preference have been elucidated. The present review delved into how industrial traits can be enhanced through directed evolution (epPCR, gene shuffling), rational design (FRESCO, ASR), combined engineering strategies (i.e. CAST, ISM, and FRISM) as protein engineering methodologies in contexts of biodiesel production, food processing, and applications of detergent, pharmaceutics, and plastic degradation.
脂肪酶是一种非常出色的生物催化剂,能够通过水解将各种化合物分解为甘油、脂肪酸、单甘酯和二甘酯。除此之外,它们还能够促进酯化、酯交换、醇解、酸解等反应,因此在工业应用中具有广泛的用途。在工业生产中,人们更倾向于使用稳定性高的脂肪酶,因为它们能够耐受恶劣的条件。然而,大多数天然脂肪酶无法耐受不良条件,因此不适合工业应用。蛋白质工程被证明是一种有效的技术,可以开发出能够在挑战性条件下有效发挥作用并满足各种工业生产要求的脂肪酶。本综述集中讨论了蛋白质工程领域的新趋势,以增强脂肪酶基因的多样性,并利用计算机模拟方法预测和全面分析脂肪酶的目标突变。此外,还阐明了与脂肪酶的工业特性相关的关键分子因素,包括热稳定性、溶剂耐受性、催化活性和底物偏好。本综述深入探讨了如何通过定向进化(epPCR、基因改组)、理性设计(FRESCO、ASR)、组合工程策略(即 CAST、ISM 和 FRISM)等蛋白质工程方法来提高脂肪酶的工业特性,这些方法在生物柴油生产、食品加工以及洗涤剂、制药和塑料降解等领域的应用中具有重要意义。
