Saposin B-dependent Reconstitution of Arylsulfatase A Activity in Vitro and in Cell Culture Models of Metachromatic Leukodystrophy

Arylsulfatase A (ASA) catalyzes the intralysosomal desulfation of 3-O-sulfogalactosylceramide (sulfatide) to galactosylceramide. The reaction requires saposin B (Sap B), a non-enzymatic proteinaceous cofactor which presents sulfatide to the catalytic site of ASA. The lack of either ASA or Sap B resu...
