Carbohydrates are widely abundant molecules present in a variety of forms. For their biosynthesis and modification, nature has evolved a plethora of carbohydrate-acting enzymes. Many of these enzymes are of particular interest for biotechnological applications, where they can be used as biocatalysts or biosensors. Among the enzymes catalysing conversions of carbohydrates are the carbohydrate oxidases. These oxidative enzymes belong to different structural families and use different cofactors to perform the oxidation reaction of CH-OH bonds in carbohydrates. The variety of carbohydrate oxidases available in nature reflects their specificity towards different sugars and selectivity of the oxidation site. Thanks to their properties, carbohydrate oxidases have received a lot of attention in basic and applied research, such that nowadays their role in biotechnological processes is of paramount importance. In this review we provide an overview of the available knowledge concerning the known carbohydrate oxidases. The oxidases are first classified according to their structural features. After a description on their mechanism of action, substrate acceptance and characterisation, we report on the engineering of the different carbohydrate oxidases to enhance their employment in biocatalysis and biotechnology. In the last part of the review we highlight some practical applications for which such enzymes have been exploited.

大量碳水化合物氧化酶:概述。

碳水化合物是广泛存在的以各种形式存在的分子。对于它们的生物合成和修饰,大自然已经进化出过多的碳水化合物作用酶。许多这些酶对生物技术应用特别感兴趣,它们可以用作生物催化剂或生物传感器。催化碳水化合物转化的酶是碳水化合物氧化酶。这些氧化酶属于不同的结构家族,利用不同的辅因子进行碳水化合物中CH-OH键的氧化反应。自然界中可用的碳水化合物氧化酶的多样性反映了它们对不同糖的特异性和氧化位点的选择性。由于它们的特性,碳水化合物氧化酶在基础和应用研究中受到了很多关注,因此,如今它们在生物技术过程中的作用至关重要。在这篇综述中,我们概述了有关已知碳水化合物氧化酶的可用知识。首先根据其结构特征对氧化酶进行分类。在描述了它们的作用机制、底物接受度和表征之后,我们报告了不同碳水化合物氧化酶的工程设计,以增强它们在生物催化和生物技术中的应用。在评论的最后一部分,我们重点介绍了这些酶已被利用的一些实际应用。在描述了它们的作用机制、底物接受度和表征之后,我们报告了不同碳水化合物氧化酶的工程设计,以增强它们在生物催化和生物技术中的应用。在评论的最后一部分,我们重点介绍了这些酶已被利用的一些实际应用。在描述了它们的作用机制、底物接受度和表征之后,我们报告了不同碳水化合物氧化酶的工程设计,以增强它们在生物催化和生物技术中的应用。在评论的最后一部分,我们重点介绍了这些酶已被利用的一些实际应用。
