Glycoside hydrolase family 30
Encyclopedia
In molecular biology, glycoside hydrolase family 30 is a family
of glycoside hydrolases
.
Glycoside 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 glycoside hydrolases, based on sequence similarity, has led to the definition of >100 different families. This classification is available on the CAZy(http://www.cazy.org/GH1.html) web site, and also discussed at CAZypedia, an online encyclopedia of carbohydrate active enzymes.
Glycoside hydrolase family 30 CAZY GH_30 includes the mammalian glucosylceramidases
. Human acid beta-glucosidase (D-glucosyl-N-acylsphingosine glucohydrolase), cleaves the glucosidic bonds of glucosylceramide and synthetic beta-glucosides. Any one of over 50 different mutations in the gene of glucocerebrosidase
have been found to affect activity of this hydrolase, producing variants of Gaucher disease, the most prevalent lysosomal storage disease.
Protein family
A protein family is a group of evolutionarily-related proteins, and is often nearly synonymous with gene family. The term protein family should not be confused with family as it is used in taxonomy....

Glucosylceramidase
In enzymology, a glucosylceramidase is an enzyme that catalyzes the chemical reactionThus, the two substrates of this enzyme are D-glucosyl-N-acylsphingosine and H2O, whereas its two products are D-glucose and N-acylsphingosine....
