WebChitin deacetylase (CDA) (EC 3.5.1.41) is a hydrolytic enzyme that belongs to carbohydrate esterase family 4 as per the CAZY database. The CDA enzyme deacetylates chitin into chitosan. As the marine ecosystem is a rich source of chitin, it would also hold the unexplored extremophiles. WebThe t(1/2) for in vitro release varied depending on the concentration of chitosan and chitin and the amount of glutaraldehyde used.
