title: Arylsulphatase C and estrone sulphatase of sheep hypothalamus, preoptic area, and midbrain: separation by hydrophobic interaction chromatography and evidence for differences in their lipid environment.
abstract: Arylsulphatase C and estrone sulphatase activities of sheep hypothalamus-preoptic area-midbrain were examined for their susceptibility to phospholipase action. Russel's viper phospholipase A could completely inactivate estrone sulphatase without affecting arylsulphatase C. The latter was partially inactivated by S. aureus phospholipase C but not by C. welchi phospholipase C. Both arylsulphatase C and estrone sulphatase were inactivated to different extents by sodium deoxycholate, which is known to activate the intrinsic phospholipases of brain. Hydrophobic interaction chromatography on phenyl-Sepharose resulted in the differential elution of arylsulphatase C and estrone sulphatase. The results suggest that one enzyme is not responsible for arylsulphatase C and estrone sulphatase activities.
