Glucose oxidase (GOx) is an important oxidoreductase enzyme with many important roles in biological processes. It is considered an "ideal enzyme" and is often called an oxidase "Ferrari" because of its fast mechanism of action, high stability and specificity. Glucose oxidase catalyzes the oxidation of β-d-glucose to d-glucono-δ-lactone and hydrogen peroxide in the presence of molecular oxygen. d-glucono-δ-lactone is sequentially hydrolyzed by lactonase to d-gluconic acid, and the resulting hydrogen peroxide is hydrolyzed by catalase to oxygen and water. GOx is presently known to be produced only by fungi and insects. The current main industrial producers of glucose oxidase are and An important property of GOx is its antimicrobial effect against various pathogens and its use in many industrial and medical areas. The aim of this review is to summarize the structure, function, production strains and biophysical and biochemical properties of GOx in light of its various industrial, biotechnological and medical applications.
葡萄糖氧化酶(GOx)是一种重要的氧化还原酶,在生物过程中具有许多重要作用。它被认为是一种“理想的酶”,由于其快速的作用机制、高稳定性和特异性,常被称为氧化酶“法拉利”。葡萄糖氧化酶在分子氧存在的情况下,催化β-d-葡萄糖氧化为 d-葡萄糖酸-δ-内酯和过氧化氢。d-葡萄糖酸-δ-内酯通过内酯酶依次水解为 d-葡萄糖酸,生成的过氧化氢被过氧化氢酶水解为氧和水。目前已知葡萄糖氧化酶仅由真菌和昆虫产生。目前葡萄糖氧化酶的主要工业生产菌为 和 。GOx 的一个重要特性是其对各种病原体的抗菌作用及其在许多工业和医疗领域的应用。本综述旨在根据葡萄糖氧化酶在各种工业、生物技术和医学应用中的结构、功能、生产菌株以及物理化学和生物化学特性进行总结。
