Abstract
A profound deficiency (10- to 30-fold) of β-galactosidase activity was found in tissues (liver, spleen, kidney, and brain) from two patients with generalized gangliosidosis; this deficiency is demonstrated as a failure to cleave both p-nitrophenyl-β-D-galactopyranoside and ganglioside GM1 labeled with C14 in the terminal galactose. We believe that this enzymic defect is responsible for the accumulation of ganglioside GM1 and is the fundamental enzyme defect in generalized gangliosidosis.This publication has 10 references indexed in Scilit:
