Abstract
A 6-sulfatase specific for sugars of the galactose configuration was purified 81-fold from the crude extract of Actinobacillus sp. IFO-13310. This preparation contained activity towards both N-acetylgalactosamine 6-sulfate and galactose 6-sulfate (relative activity, 2.4 : 1). The enzyme also released inorganic sulfate from the non-reducing galactose 6-sulfate end group of a trisaccharide disulfate prepared from keratan sulfate by sequential degradation with endo-β-galactosidase, N-acetylglucosamine-6-sulfatase and exo- β- N-acetylglucosaminidase. In addition, a tetrasaccharide trisulfate bearing the non-reducing N-acetylglucosamine 6-sulfate end group, also enzymatically prepared from keratan sulfate, was degraded to give rise to inorganic sulfate, N-acetylglucosamine and galactose by the sequential action of this enzyme, N-acetylglucosamine-6-sulfatase, exo- β- N-acetylglucosaminidase and exo-β-galactosidase ( Charonia lampas).
