α-Amylase is the most significant glycoside hydrolase having applications in various industries. It cleaves the α,1-4 glucosidic linkages of polysaccharides like starch, glycogen to yield a small polymer of glucose in α-anomeric configuration. α-Amylase is produced by all the three domains of life but microorganisms are preferred sources for industrial-scale production due to several advantages. Enormous studies and research have been done in this field in the past few decades. Still, it is requisite to work on enzyme stability and catalysis, as it loses its functionality in extreme. As the enzyme loses its structural and catalytic property under extreme environmental conditions, it is mandatory to confer some potential strategies for enhancing enzyme behaviour in such conditions. This limitation of an enzyme can be overcome up to some extent by extremophiles. They serve as an excellent source of α-amylase with outstanding features. This review is an attempt to encapsulate some structure-based strategies for improving enzyme behaviour thereby enabling researchers to selectively amend any of the strategies as per requirement during upstream and downstream processing for higher enzyme yield and stability. Thus, it will provide some cutting-edge strategies for tailoring α-amylase producing organism and enzyme with the help of several computational biology tools.
α-淀粉酶是最重要的糖苷水解酶,在许多行业中有应用。它能切割淀粉、糖原等多糖中的α,1-4 糖苷键,生成具有α-构型的葡萄糖小聚合物。α-淀粉酶存在于生命的三个领域,但由于其具有多种优势,微生物是工业规模生产的首选来源。在过去几十年中,该领域进行了大量的研究和探索。然而,仍需要研究酶的稳定性和催化作用,因为在极端条件下,酶会失去功能。由于酶在极端环境条件下会失去结构和催化特性,因此必须提出一些潜在的策略来增强酶在这种条件下的行为。在某种程度上,极端微生物可以克服酶的这种局限性。它们是具有突出特性的α-淀粉酶的极好来源。本文综述了一些基于结构的策略,以改善酶的行为,从而使研究人员能够根据需要在上下游处理过程中选择性地采用任何策略,以提高酶的产量和稳定性。因此,它将提供一些前沿的策略,以帮助利用多种计算生物学工具来定制产α-淀粉酶的生物体和酶。
