Single-mutations at the galactose-binding site of enzymes GalK, GalU, and LgtC enable the efficient synthesis of UDP-6-azido-6-deoxy-d-galactose and azido-functionalized Gb3 analogs.

Abstract excerpt

Lysosomal accumulation of the glycosphingolipid globotriaosylceramide Gb3 is linked to the deficient activity of the α-galactosidase A in the Anderson-Fabry disease and an elevated level of deacylated Gb3 is a hallmark of this condition. Localization of Gb3 in the plasma membrane is critical for studying how the membrane organization and its dynamics are affected in this genetic disorder. Gb3 analogs containing a...
