PFAM accession number:PF01055
Interpro abstract (IPR000322):

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 [(PUBMED:7624375), (PUBMED:8535779)]. This classification is available on the CAZy (CArbohydrate-Active EnZymes) web site.

Glycoside hydrolase family 31 comprises enzymes with several known activities; alpha-glucosidase (EC, alpha-galactosidase (EC; glucoamylase (EC, sucrase-isomaltase (EC; isomaltase (EC; alpha-xylosidase (EC 3.2.1); alpha-glucan lyase (EC

Glycoside hydrolase family 31 groups a number of glycosyl hydrolases on the basis of sequence similarities [(PUBMED:1747104), (PUBMED:1761061), (PUBMED:1743281)]. An aspartic acid has been implicated [(PUBMED:1856189)] in the catalytic activity of sucrase, isomaltase, and lysosomal alpha-glucosidase.

GO process:carbohydrate metabolic process (GO:0005975)
