Hydrolases are classified as EC 3 in the EC number classification of enzymes. Hydrolases can be further classified into several subclasses, based upon the bonds they act upon: EC 3.1: ester bonds (esterases: nucleases, phosphodiesterases, lipase, phosphatase) EC 3.2: sugars (DNA glycosylases, glycoside hydrolase) EC 3.3: ether bonds
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 ...
Function: Amylase is an enzyme that is responsible for the breaking of the bonds in starches, polysaccharides, and complex carbohydrates to be turned into simple sugars that will be easier to absorb. Clinical Significance: Amylase also has medical history in the use of Pancreatic Enzyme Replacement Therapy (PERT). One of the components is ...
Glycoside hydrolases are typically named after the substrate that they act upon. Thus glucosidases catalyze the hydrolysis of glucosides and xylanases catalyze the cleavage of the xylose based homopolymer xylan. Other examples include lactase, amylase, chitinase, sucrase, maltase, neuraminidase, invertase, hyaluronidase and lysozyme.
An acid hydrolase is an enzyme that works best at acidic pHs.It is commonly located in lysosomes, which are acidic on the inside.Acid hydrolases may be nucleases, proteases, glycosidases, lipases, phosphatases, sulfatases and phospholipases and make up the approximately 50 degradative enzymes of the lysosome that break apart biological matter.
Because a phosphatase enzyme catalyzes the hydrolysis of its substrate, it is a subcategory of hydrolases. [1] Phosphatase enzymes are essential to many biological functions, because phosphorylation (e.g. by protein kinases) and dephosphorylation (by phosphatases) serve diverse roles in cellular regulation and signaling.

Hydrolases catalyze the hydrolysis of various chemical bonds. They are classified as EC 3 in the EC number classification. Wikimedia Commons has media related to Hydrolases .
In molecular biology, Glycoside hydrolase family 10 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 ...
