This fellowship will be used to establish a multidisciplinary team working at the interface of chemistry, biology and protein engineering at the University of York, UK. The overarching goal of my group's research will be to develop novel approaches for biopolymer synthesis, design and discovery. In the process, we want to unravel the mechanisms that control and modulate the behavior of enzymes and proteins. The methodologies developed and insights gained through this proposal will inform the synthesis strategies for a new generation of therapeutics and biomaterials. Chemical synthesis remains the mainstay for the production of drugs, including the modern, next generation biologics composed of peptides, proteins, DNA, RNA, carbohydrates and their conjugates. Biomolecular conjugates have also found use as nanomaterials, drug delivery vehicles and components of biocomputers. Traditional chemical methods of synthesis require harsh conditions such as high temperature, non-aqueous solvents and non-physiological pH - parameters that are often incompatible with the manufacture of biomolecules. It is therefore imperative that alternative, sustainable strategies are explored. Enzymes present a biocompatible mode of synthesis that is starting to be exploited for the manufacture of biomolecular drugs. In this proposal, my research group will focus on adapting natural enzymes to perform the synthesis of a commonly used hybrid biomolecule - peptide-oligonucleotide conjugate. The knowledge gained will be used to further expand the existing repertoire of biologics and biomaterials.

该奖学金将用于在英国约克大学建立一个跨学科团队，从事化学、生物学和蛋白质工程的研究。我小组研究的首要目标是开发生物聚合物合成、设计和发现的新方法。在此过程中，我们希望揭示控制和调节酶和蛋白质行为的机制。通过该提案开发的方法和获得的见解将为新一代治疗方法和生物材料的合成策略提供信息。化学合成仍然是药物生产的支柱，包括由肽、蛋白质、DNA、RNA、碳水化合物及其缀合物组成的现代下一代生物制剂。生物分子缀合物也可用作纳米材料、药物输送载体和生物计算机组件。传统的化学合成方法需要苛刻的条件，例如高温、非水溶剂和非生理 pH 参数，这些参数通常与生物分子的制造不相容。因此，当务之急是探索替代的、可持续的战略。酶提供了一种生物相容性合成模式，开始用于生物分子药物的制造。在这项提案中，我的研究小组将重点研究利用天然酶来合成常用的混合生物分子——肽-寡核苷酸缀合物。所获得的知识将用于进一步扩展现有的生物制品和生物材料。
