Glycoside hydrolases (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 numerous different ...
Glycoside hydrolases are classified into EC 3.2.1 as enzymes catalyzing the hydrolysis of O- or S-glycosides. Glycoside hydrolases can also be classified according to the stereochemical outcome of the hydrolysis reaction: thus they can be classified as either retaining or inverting enzymes. [ 6 ]
In molecular biology, Glycoside hydrolase family 14 is a family of glycoside hydrolases. Glycoside 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 glycoside hydrolases, based on ...
Miglitol is an oral alpha-glucosidase inhibitor used in the treatment of type 2 diabetes. It works by reversibly inhibiting alpha-glucosidase enzymes in the small intestine, which delays the digestion of complex carbohydrates and subsequently reduces postprandial glucose levels. [ 1 ]
In molecular biology, Glycoside hydrolase family 2 is a family of glycoside hydrolases EC 3.2.1., which 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 ...
Most forms of the enzyme can rapidly hydrolyse 1,6-α-D-glucosidic bonds when the next bond in the sequence is 1,4. They belong to a variety of different families, such as glycoside hydrolase family 15 in fungi, glycoside hydrolase family 31 of human intestine MGAM, and glycoside hydrolase family 97 of bacterial forms. It was also known as γ ...
The definition associated with Enzyme Commission number 3.2.1.20 is narrower. It requires the linkage to be 1→4, and the preferred substrate to be smaller oligosaccharides (as opposed to larger polysaccharides like starch: alpha-amylase would otherwise be included).
There are many characterised protein families with Glycoside hydrolase activity EC 3.2.1..These enzymes hydrolyse the glycosidic bond between two or more carbohydrates, or between a carbohydrate and a non-carbohydrate moiety.
