Extracts of normal human livers and skin fibroblasts cultured from normal individuals and patients with the Hurler syndrome released L-iduronic acid when incubated with desulfated dermatan sulfate. Enzyme extracts of normal fibroblasts liberated larger amounts of L-induronic acid, as judged by paper chromatography, than did homogenates from Hurler fibroblasts. Preliminary studies with desulfated heparan sulfate using the same enzyme systems have also shown material with the Rf of iduronolactone on paper chromatography.
