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

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

The α-galactosidase AgaA from the thermophilic microorganism Geobacillus stearothermophilus has great industrial potential because it is fully active at 338 K against raffinose and can increase the yield of manufactured sucrose. AgaB has lower affinity for its natural substrates but

Fabry disease (FD) is a rare, X-linked lysosomal storage disorder with multiorgan involvement. FD is caused by a partial or total deficit of α-galactosidase A enzyme, which is responsible for the accumulation of glycosphingolipids in a variety of cell types.

Fabry disease is an X-linked lysosomal disorder resulting from mutations in the α-galactosidase A (GLA) gene. Recent reports described that the E66Q mutation of GLA is not a disease-causing mutation. However, no pathological study was reported. We carried out pathological
