title: Age-dependent modulation of 3'-phosphoadenosine-5'-phosphosulfate-galactosylceramide sulfotransferase by lipids extracted from the microsomal membranes and artificial lipid mixtures.
abstract: The 3'-phosphoadenosine-5'-phosphosulfate-galactosylceramide-sulfotransferase (cerebroside sulfotransferase) is microsomal enzyme, which shows a definite developmental activity pattern. This report gives evidence that the enzyme activity of partially delipidated microsomes is modulated by the cholesterol:phospholipid ratio of the extracted microsomal lipids in an age-dependent manner. These findings suggest that in vivo the enzyme activity is modulated by the lipid surrounding.
