| Type: | Active_site | Name: | Glycosyl hydrolases family 31, active site |
| Description: | 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.The region around this active residue is highly conserved and is represented in this entry. | Short Name: | Glyco_hydro_31_AS |
