WebDec 6, 2024 · Abstract Purpose: Food allergy is a hypersensitive immune response to specific food proteins. Chitinase 3-like 1 (CHI3L1, also known as YKL-40 in humans or BRP-39 in mice) is associated with various chronic diseases, such as cancer, rheumatoid arthritis, and allergic disease. WebChitosanase (EC 3.2.1.132) is described as a hydrolytic enzyme responsible for chitosan depolymerization and catalyzes the cleavage of β-1,4-linked glycosidic linkage in the chitosan.
