Glycoside Hydrolase Family 1
Glycoside hydrolase family 1 is a Protein family, 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 web site, and also discussed at CAZypedia, an online encyclopedia of carbohydrate active enzymes. Glycoside hydrolase family CAZY GH_1comprises enzymes with a number of known activities; beta-glucosidase (); beta-galactosidase (); 6-phospho-beta-galactosidase (); 6-phospho-beta-glucosidase (); Glycosylceramidase, lactase-phlorizin hydrolase (), lactase (); beta-mannosidase (); myrosinase (). Subfamilies *6-phospho-beta-galactosidase Human proteins containing this domain GBA3; KL (gene), KL; KLB (gene), KLB; Lactase, LCT; ...

Protein Family
A protein family is a group of evolutionarily related proteins. In many cases, a protein family has a corresponding gene family, in which each gene encodes a corresponding protein with a 1:1 relationship. The term "protein family" should not be confused with family as it is used in taxonomy. Proteins in a family descend from a common ancestor and typically have similar three-dimensional structures, functions, and significant sequence similarity. Sequence similarity (usually amino-acid sequence) is one of the most common indicators of homology, or common evolutionary ancestry. Some frameworks for evaluating the significance of similarity between sequences use sequence alignment methods. Proteins that do not share a common ancestor are unlikely to show statistically significant sequence similarity, making sequence alignment a powerful tool for identifying the members of protein families. Families are sometimes grouped together into larger clades called superfamilies based on st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
