Galactosidases are enzymes (glycoside hydrolases) that catalyze the hydrolysis of galactosides into monosaccharides.. Galactosides can be classified as either alpha or beta. If the galactoside is classified as an alpha-galactoside, the enzyme is called alpha-galactosidase, and is responsible for catalyzing the hydrolysis of substrates that contain α-galactosidic residues, such as ...
α-Galactosidase ( EC 3.2.1.22, α-GAL, α-GAL A; systematic name α-D-galactoside galactohydrolase) is a glycoside hydrolase enzyme that catalyses the following reaction: [1] Hydrolysis of terminal, non-reducing α- D -galactose residues in α- D -galactosides, including galactose oligosaccharides, galactomannans and galactolipids
Structure of ONPG, an example of a β-galactoside. Depending on whether the glycosidic bond lies "above" or "below" the plane of the galactose molecule, galactosides are classified as α-galactosides or β-galactosides. A β-galactoside is a type of galactoside in which the glycosidic bond lies above the plane of the galactose residue.
A recent study conducted in 2020–2021 determined that Beta-Galactosidase activity correlates with senescence of the cells. Senescence of the cells can be interpreted as cells that do not divide, but cells that do not die. Beta-Galactosidase activity can be overexpressed, and this can lead to various diseases afflicting a wide range of body ...
Galactosidase alpha is an enzyme that in humans is encoded by the GLA gene. [5] Two recombinant forms of human α-galactosidase are called agalsidase alpha and agalsidase beta (INN). [6] A mold-derived form is the primary ingredient in gas relief supplements. [citation needed]
One known example of these transport proteins is the melibiose, or melB, carrier protein derived from the melB gene of E. coli. [3] This strain of beta-galactoside permease is known it transport melibiose and other galactosides across the cell membrane using hydrogen , sodium , or lithium ions in cotransport .

In molecular biology, glycoside hydrolase family 42 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.
