Abstact

β-1,3-Glucan is one of the most abundant polysaccharides in fungi. Recognition of β-1,3-glucan occurs in both hydrolysis by glycoside hydrolases and immunological recognition. Our study provides a novel structural account of how glycoside hydrolase recognizes and hydrolyzes substrates in a triple-helical form and presents a general structural basis of β-1,3-glucan recognition.
