The various folding patterns of the pol3rpeptide chain constituting the catalytic domains of glycoside hydrolase families have been reviewed [4], At the time of writing three-dimensional structures are available for members of over 31 hydrolase families and one unclassified hydrolase and three families of glycosyl transferases and one unclassified (Bernard Henrissat, personal communication). 

The catalytic residues of a large number of glycoside hydrolase families have been identified by various means, as described below. These identities have been summarized in a recent review. ...

Enzymes classified into oxazoline intermediate type are typically chitinase and hyaluronidase. Chitinase from Bacillus sp. (EC 3.2.1.14) belonging to the glycoside hydrolase family 18 primarily catalyzes hydrolysis of (1— 4)-jff-A-acetylglucosaminide linkage in chitin (30,32,33). The hydrolysis mechanism is postulated to proceed through the substrate-assisted mechanism as follows (Figure 3).

Polysaccharide monoojygenases have long been classified as Glycoside Hydrolase family 61 (GH-61) because weak endoglucanase activity had been observed. These experimental results might be explained by the fact that chain breaks introduced near the reducing end will release soluble native cello-oligosaccharides. Nevertheless, this classification is incorrect since an...
