    Protein Summary

    The gene TM1192 from Thermotoga maritima encodes a alpha-galactosidase (specifically alpha-1,6-galactosidase) COG3345, a member of melibiases family PF02065.  The enzyme contains a domain adopting a  supersandwich fold type SCOP49993.  The enzyme is a homodimeric glycoprotein that hydrolyses the terminal alpha-galactosyl moieties from glycolipids and glycoproteins. It predominantly hydrolyzes ceramide trihexoside, and it can catalyze the hydrolysis of melibiose into galactose and glucose.  In humans (3HG3 3HG4),  a variety of mutations in this gene affect the synthesis, processing, and stability of this enzyme, which causes Fabry's disease, a rare lysosomal storage disorder and sphingolipidosis that results from a failure to catabolize alpha-D-galactosyl glycolipid moieties.
