蛋白质工程的研究进展与应用摘要：蛋白质是生命活动的主要承担者，是参与生物生长，发育，代谢，繁殖的重要生物大分子。随着生物化学及分子生物学的发展，蛋白质工程被广泛研究，通过物理，化学，分子生物学等手段对现有的蛋白质进行改造、修饰从而优化其性质，或合成自然界中不存在的具有新功能的蛋白质，可更好地满足人们的需要。蛋白质工程技术已在药物研发，农业生产等领域广泛应用，并取得了显著成效，本文综述了蛋白质工程的原理，方法，研究进展及应用，并展望其发展前景。旨在强调其在生物科学领域深远的研究意义及重要的应用价值。关键词：蛋白质工程，分子生物学，定点突变，定向演化Research progress and application of protein engineeringAbstract: Protein is the main undertaker of life activities and an important biological macromolecule involved in biological growth, development, metabolism and reproduction. With the development of biochemistry and molecular biology, protein engineering has been widely studied. It can better meet the needs of people through physical, chemical, molecular biology and other means to modify and modify the existing proteins to optimize their properties, or to synthesize proteins with new functions that do not exist in nature. Protein engineering technology has been widely used in drug research and development, agricultural production and other fields, and achieved remarkable results. In this paper, the principle, method, research progress and application of protein engineering were reviewed, and its development prospect was prospected. The purpose was to emphasize its profound research significance and important application value in the field of biological science.Keywords: Protein engineering; molecular biology; site-directed mutation; directed evolution引言蛋白质工程是以蛋白质的分子结构与生物功能的关系为基础，利用物理，化学及分子生物学等手段进行基因修饰或基因合成，从而获得经改造后功能更加完善的蛋白质或自然中原本不存在的新...
