| Type: | Family | Name: | Glycoside hydrolase family 31 |
| Description: | O-Glycosyl hydrolases () 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 [, ]. This classification is available on the CAZy (CArbohydrate-Active EnZymes) web site.Glycoside hydrolase family 31 comprises enzymes with several known activities; alpha-glucosidase (), alpha-galactosidase (); glucoamylase (), sucrase-isomaltase (); isomaltase (); alpha-xylosidase (); alpha-glucan lyase (). Glycoside hydrolase family 31 groups a number of glycosyl hydrolases on the basis of sequence similarities [, , ].An aspartic acid has been implicated [] in the catalytic activity of sucrase,isomaltase, and lysosomal alpha-glucosidase. | Short Name: | Glyco_hydro_31 |
