一般說明
Alkaline α-Galactosidase I is a glycoside hydrolase, separated from the extracts of melon fruits. The activity of this enzyme is found to increase during the early stages of ovary development and fruit set.[1]
應用
Alkaline α-Galactosidase I was used to assay enzyme activity with 2 mmp-nitrophenyl-α-d-galactoside as substrate at pH 6.5 to compare with the enzyme activity of α-Gal A isolated and purified from Sf-9 insect cells infected with a recombinant baculovirus encoding normal α-Gal A gene.[2]
生化／生理作用
α-Galactosidase form I from melon may play a significant role in photoassimilate partitioning in sink tissue. The form I enzyme has a preferred activity with raffinose and significant activity with stachyose. A unique feature of this enzyme is that it exhibits weak product inhibition by galactose.
This enzyme shows a preference for raffinose and also activity with stachyose. Unlike other a-Galctosidases, this enyzme also shows weak inhibition by galactose.
物理性質
This enzyme exhibits maximal activity between 30-37°C. Activity declines above 40°C.
單位定義
One unit will hydrolyze 1.0 μmole of p-nitrophenyl α-D-galactoside to p-nitrophenol and D-galactose per minute at pH 7.8 at 30 °C.
外觀
The product is supplied as a lyophilized powder containing Tris-HCl buffer salts, DTT, EDTA, and NaCl.

Fabry disease is a lysosomal storage disorder caused by deficient lysosomal alpha-galactosidase A (alpha-Gal A) activity. Deficiency of the enzyme activity results in progressive deposition of neutral glycosphingolipids with terminal alpha-galactosyl residue in vascular endothelial cells. We recently proposed a

The cucurbits translocate the galactosyl-sucrose oligosaccharides raffinose and stachyose, therefore, alpha-galactosidase (alpha-D-galactoside galactohydrolase, EC 3.2.1.22) is expected to function as the initial enzyme of photoassimilate catabolism. However, the previously described alkaline alpha-galactosidase is specific for the tetrasaccharide stachyose, leaving raffinose

Raffinose and stachyose are ubiquitous galactosyl-sucrose oligosaccharides in the plant kingdom which play major roles, second only to sucrose, in photoassimilate translocation and seed carbohydrate storage. These sugars are initially metabolised by alpha-galactosidases (alpha-gal). We report the cloning and functional
