Research progress on structure, function and application of β-1, 3-glucanases
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.
