DESCRIPTION

α-Galactosidase (Penicillium simplicissimum)

EC 3.2.1.22
CAZy Family: GH27
CAS: 37288-54-3

Synonyms:
alpha-D-galactoside galactohydrolase

Form:
In 3.2 M ammonium sulphate.

Stability:
> 2 years at 4oC. 

Specific activity:
~ 160 U/mg (40oC, pH 3.5 on p-nitrophenyl-α-D-galactopyranoside)

Unit definition:
One Unit of α-galactosidase activity is defined as the amount of enzyme required to release one µmole of of p-nitrophenol per minute from p-nitrophenyl-α-D-galactopyranoside (5 mM) in glycine buffer (100 mM), pH 3.5 at 40oC.

Specificity:
Hydrolysis of terminal, non-reducing α-D-galactose residues in α-D-galactosides, including galacto-oligosaccharides and galactomannans.

Applications:
For use in glycobiology, carbohydrate or biofuels research.

α-D-galactosidase activity and galactomannan and galactosylsucrose oligosaccharide depletion in germinating legume seeds.
