General description

α-Galactosidase from green coffee beans is encoded by the GLA gene.[1]

Application

α-Galactosidase from green coffee beans has been used to assess the specificity of anti- α-Galactosidase antibodies.[2][3] It has also been used in inhibition assay to assess N-guanidino derivatives of 1,5-dideoxy-1,5-imino-d-xylitol activity.[4][5]

Biochem/physiol Actions

α-Galactosidase from green coffee beans cleaves the terminal α-galactose from the oligosaccharides.[6] α-Galactosidase deficiency is associated with Fabry disease.[1]

Physical form

Suspension in 3.2 M (NH4)2SO4 solution, pH 6.0, containing BSA

Other Notes

One unit will hydrolyze 1.0 μmole of p-nitrophenyl α-D-galactoside to p-nitrophenol and D-galactose per min at pH 6.5 at 25 °C.
