It is metabolized by alpha-galactosidase, which hydrolyzes the terminal alpha linkage.
Defects in the enzyme alpha-galactosidase lead to the buildup of globotriaosylceramide, causing Fabry's disease. The pharmaceutical drug migalastat enhances the function of alpha-galactosidase and is used to treat Fabry's.
The bacterial Shiga toxin can be used for targeted therapy of gastric cancer, because this tumor entity expresses the receptor of the Shiga toxin. For this purpose an unspecific chemotherapeutical is conjugated to the B-subunit to make it specific. In this way only the tumor cells, but not healthy cells should be destroyed during therapy.
