IPR016283 is a Glycoside hydrolase, family 19.
<p>O-Glycosyl hydrolases ([ec:3.2.1.]) are a widespread group of enzymes that hydrolyse the glycosidic bond between two or more carbohydrates, or between a carbohydrate and a non-carbohydrate moiety. A classification system for glycosyl hydrolases, based on sequence similarity, has led to the definition of 85 different families [[cite:PUB00004870], [cite:PUB00005266]]. This classification is available on the CAZy (CArbohydrate-Active EnZymes) website.</p> <p>Glycoside hydrolase family 19 [cazy:GH19] comprises enzymes with only one known activity; chitinase ([ec:3.2.1.14]).</p> <p>Chitinases [[cite:PUB00001488]] are enzymes that catalyze the hydrolysis of the beta-1,4-N-acetyl-D-glucosamine linkages in chitin polymers. Chitinases belong to glycoside hydrolase families 18 or 19 [[cite:PUB00000503]]. Chitinases of family 19 (also known as classes IA or I and IB or II) are enzymes from plants that function in the defence against fungal and insect pathogens by destroying their chitin-containing cell wall. Class IA/I and IB/II enzymes differ in the presence (IA/I) or absence (IB/II) of a N-terminal chitin-binding domain. The catalytic domain of these enzymes consist of about 220 to 230 amino acid residues. The At2g43600 protein from Arabidopsis thaliana is presumably inactive as a chitinase because it lacks the Glu residue that is essential for catalytic activity.</p>
