Conserved Site

Glycosyl hydrolases family 31, conserved site (IPR030459)

Short name: Glyco_hydro_31_CS


Glycoside hydrolase family 31 GH31 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 [PMID: 1747104, PMID: 1761061, PMID: 1743281]. An aspartic acid has been implicated [PMID: 1856189] in the catalytic activity of sucrase, isomaltase, and lysosomal alpha-glucosidase.

This entry represents a conserved site in proteins of the glycoside hydrolase family 31. It contains two conserved cysteines.
