Title: a-Galactosidase A
Synonyms: 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
