摘要: β-1,3-葡聚糖酶是一类能够特异性水解β-1,3-葡聚糖中β-1,3-糖苷键的酶类,生成的产物为一系列不同大小的寡糖或单糖。β-1,3-葡聚糖酶在食品功能寡糖制备、果蔬保鲜、生物医药、植物抗病等领域具有重要应用价值。已发现的β-1,3-葡聚糖酶主要归属于12 个糖苷水解酶家族(glycoside hydrolases, GH),包括GH16、GH17、GH55、GH64、GH81、GH128和GH132等。β-1,3-葡聚糖酶广泛存在于细菌、真菌、植物和昆虫中,因来源和序列进化关系的差异,其结构和催化功能也呈现多样性。酶的结构与功能是探索酶催化反应机理、挖掘酶催化特性以及酶分子改造研究的基础。因此,本文从β-1,3-葡聚糖酶的结构、功能及应用等方面,对国内外β-1,3-葡聚糖酶的研究现状进行综述,以期为β-1,3-葡聚糖酶相关基础研究及应用开发提供参考。

Abstract: β-1,3-Glucanase, which has important potential applications in functional oligosaccharide preparation, fruit and vegetable preservation, biopharmaceuticals and plant disease resistance, specifically hydrolyzes β-1,3-glycosidic linkages in β-1,3-glucan, generating a range of oligosaccharides or monosaccharides. The known β-1, 3-glucanases belong to 12 glycoside hydrolases (glycoside hydrolases, GH) families, including GH16, GH17, GH55, GH64, GH81, GH128 and GH132, et al. β-1,3-Glucanases are widely distributed in bacteria, fungi, plants and insects, which exhibit diversified structures and catalytic functions due to differences in sources and sequence evolution. Structural and functional studies of enzymes are the basis for exploring the catalytic mechanism, enzyme properties, and molecular modification. ?Therefore, this paper reviews the domestic and abroad current research progress on structure, function and application of β-1, 3-glucanases, in order to provide references for theoretical research and application development related to β-1,3-glucanases.
