Recent developments in chitosanase research and its biotechnological applications: a review.
Thadathil N, Velappan SP. Thadathil N, et al. Food Chem. 2014 May 1;150:392-9. doi: 10.1016/j.foodchem.2013.10.083. Epub 2013 Oct 26. Food Chem. 2014. PMID: 24360467 Review.
Chitosanases (EC 3.2.1.132) are glycosyl hydrolases that catalyse the endohydrolysis of beta-1,4-glycosidic bonds of partially acetylated chitosan to release chitosan oligosaccharides (COS). Chitosanases are isolated, purified and characterised from different source …
