The disease is caused by a defect in the housekeeping gene for lysosomal glucocerebrosidase (also known as beta-glucosidase, EC 3.2.1.45 ) on the first chromosome (1q22). The enzyme is a 55.6- kilodalton , 497- amino acid -long protein that catalyses the breakdown of glucocerebroside, a cell membrane constituent of red and white blood cells .
Amygdalin is classified as a cyanogenic glycoside, because each amygdalin molecule includes a nitrile group, which can be released as the toxic cyanide anion by the action of a beta-glucosidase. Eating amygdalin will cause it to release cyanide in the human body, and may lead to cyanide poisoning .
Beta-glucosidase # EC 3.2.1.21 : is associated with Gaucher's disease: Lactase: EC 3.2.1.23 : one member of the β-galactosidase family, breaks down milk sugars, and its absence in adulthood causes lactose intolerance: Debranching enzyme # EC 3.2.1.33: in mammals, yeast and some bacteria, combines transferase and glucosidase activity in ...
“There are more than 200 types of cancer, with lots of possible symptoms,” says Dr Julie Sharp, head of health and patient information at CRUK. “It’s impossible to know them all, which is ...
β-Glucosidase (EC 3.2.1.21; systematic name β-D-glucoside glucohydrolase) is an enzyme that catalyses the following reaction: [2] Hydrolysis of terminal, non-reducing β- D -glucosyl residues with release of β- D -glucose
β-Glucocerebrosidase (also called acid β-glucosidase, D-glucosyl-N-acylsphingosine glucohydrolase, or GCase) is an enzyme with glucosylceramidase activity (EC 3.2.1.45) that cleaves by hydrolysis the β-glycosidic linkage of the chemical glucocerebroside, an intermediate in glycolipid metabolism that is abundant in cell membranes (particularly skin cells).

The GM1 gangliosidoses, usually shortened to GM1, are gangliosidoses caused by mutation in the GLB1 gene resulting in a deficiency of beta-galactosidase.The deficiency causes abnormal storage of acidic lipid materials in cells of the central and peripheral nervous systems, but particularly in the nerve cells, resulting in progressive neurodegeneration.
