Cleaves α(1→3)- and α(1→6)-linked, non-reducing terminal galactose from complex carbohydrates and glycoproteins. It is particularly efficient for removing α-linked galactose under conditions where the pH must be neutral or above, for example, with live cells.

Unit Definition

One unit will hydrolyze 1 μmole of p-nitrophenyl α-D-galactopyranoside per min at pH 6.5 at 25 °C.

Physical form

This product is a sterile-filtered aqueous buffered solution.

The utilization by Escherichia coli K12 of raffinose as sole carbon source depends on a new raffinose transport system, an invertase and an alpha-galactosidase specified by the Raf-plasmid D1021. The alpha-galactosidase was purified to homogeneity from a mutant strain with...

Enzymatical conversion of A or B RBCs into group O RBCs (ECORBCs) was achieved by using α-N-acetylgalactosaminidase and α-galactosidase, respectively. Now, we initiated AB to O-RBC conversion by using these two enzymes together. But α-N-acetylgalactosaminidase and α-galactosidase's preserving and their...

Fabry disease (FD) is a genetic disorder resulting from deficiency of the lysosomal enzyme α-galactosidase A (α-Gal A), which leads to globotriaosylceramide (GL-3) accumulation in multiple tissues. We report on the safety and pharmacodynamics of migalastat hydrochloride, an investigational pharmacological...
