The surface chemistry, pendent functional entities, and ease in tunability of various materials play a central role in properly coordinating with enzymes for immobilization purposes. Due to the interplay between the new wave of support matrices and enzymes, the development of robust biocatalytic constructs via protein engineering expands the practical scope and tunable catalysis functions. The concept of stabilization via functional entities manipulation, the surface that comprises functional groups, such as thiol, aldehyde, carboxylic, amine, and epoxy have been the important driving force for immobilizing purposes. Enzyme immobilization using multi-functional supports has become a powerful norm and presents noteworthy characteristics, such as selectivity, specificity, stability, resistivity, induce activity, reaction efficacy, multi-usability, high catalytic turnover, optimal yield, ease in recovery, and cost-effectiveness. There is a plethora of literature on traditional immobilization approaches, e.g., intramolecular chemical (covalent) attachment, adsorption, encapsulation, entrapment, and cross-linking. However, the existing literature is lacking state-of-the-art smart chemistry of immobilization. This review is a focused attempt to cover the literature gap of surface functional entities that interplay between support materials at large and enzyme of interest, in particular, to tailor robust biocatalysts to fulfill the growing and contemporary needs of several industrial sectors.
表面化学、悬垂官能团以及各种材料的易调理性在与酶适当协调以实现固定化目的方面起着核心作用。由于新型支撑基质和酶之间的相互作用,通过蛋白质工程开发稳健的生物催化构建体扩展了实际范围和可调催化功能。通过官能团操纵进行稳定化的概念、包含巯基、醛基、羧基、胺基和环氧等官能团的表面,一直是固定化目的的重要驱动力。使用多功能载体进行酶固定化已成为一种强大的规范,并呈现出选择性、特异性、稳定性、抗阻性、诱导活性、反应效果、多用性、高催化周转率、最佳产量、易于回收和成本效益等显著特点。关于传统固定化方法的文献很多,例如分子内化学(共价)附着、吸附、包封、包埋和交联。然而,现有的文献缺乏固定化的最新智能化学。本综述旨在重点填补表面官能团文献空白,即支撑材料与目标酶之间的相互作用,特别是定制稳健的生物催化剂以满足几个工业部门不断增长和现代的需求。
