β-Galactosidase is an exoglycosidase which hydrolyzes the β-glycosidic bond formed between a galactose and its organic moiety. It may also cleave fucosides and arabinosides but at a much lower rate. It is an essential enzyme in the human body. Deficiencies in the protein can result in galactosialidosis or Morquio B syndrome.
When the target gene is not found in the vector, the alpha fragment gene would be active, producing the alpha fragment and allowing for B-galactosidase to gain its activity. To trace the activity of B-galactosidase a colorless analog of lactose is used, X-gal. The hydrolysis of X-gal by B-galactosidase produces galactose, a blue colored compound.
Fabry disease, also known as Anderson–Fabry disease, is a rare genetic disease that can affect many parts of the body, including the kidneys, heart, brain, and skin. [1] Fabry disease is one of a group of conditions known as lysosomal storage diseases .
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
Lactase (EC 3.2.1.108) is an enzyme produced by many organisms and is essential to the complete digestion of whole milk.It breaks down the sugar lactose into its component parts, galactose and glucose.
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 ( INN ) and agalsidase beta (INN). [ 6 ]
Beano contains the enzyme α-Galactosidase, specifically one derived from the fungus Aspergillus niger.The enzyme works in the digestive tract to break down the complex or branching sugars (polysaccharides and oligosaccharides) in foods such as legumes (beans and peanuts) and cruciferous vegetables (cauliflower, broccoli, cabbage, and brussels sprouts, among others).
Galactosidase, beta 1, also known as GLB1, is a protein which in humans is encoded by the GLB1 gene. [ 5 ] [ 6 ] The GLB1 protein is a beta-galactosidase that cleaves the terminal beta- galactose from ganglioside substrates and other glycoconjugates. [ 7 ]
