Abstract

Extracts of cultured normal human skin fibroblasts released radioactivity from a ¹⁴C-labeled heptasaccharide prepared by addition of [ ¹⁴C]N-acetylgalactosamine to the nonreducing terminus of a hexasaccharide derived from chondroitin 4-sulfate whereas fibroblast extracts from patients with Tay-Sachs and Sandhoff-Jatzkewitz diseases did not. The results suggest that N-acetyl-β-hexosaminidase A is responsible for degradation of the oligosaccharide substrate.
