alpha-Galactosidase A

Title: a-Galactosidase A
Additional Names: Ceramide trihexosidase
Literature References: Lysosomal enzyme that hydrolyzes terminal a-D-galactose residues in oligosaccharides and galactolipids. Genetic deficiency of the enzyme results in the glycosphingolipid storage disorder known as Fabry's disease. Homodimeric glycoprotein, mol wt ~101 kDa. Targeted to lysosomes via the mannose-6-phosphate receptor. Identification and role in disease: R. O. Brady et al., N. Engl. J. Med. 276, 1163 (1967). Identification as an a-galactosidase: J. A. Kint, Science 167, 1268 (1970). Use in enzyme replacement therapy: R. J. Desnick et al., Proc. Natl. Acad. Sci. USA 76, 5326 (1979). Review: R. J. Desnick et al. in The Metabolic and Molecular Bases of Inherited Disease, C. R. Scriver et al., Eds. (McGraw-Hill, New York, 7th Ed., 1995) pp 2741-2784.
