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) website.

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)
