Arylsulfatase A (or cerebroside-sulfatase) is an enzyme that breaks down sulfatides, namely cerebroside 3-sulfate into cerebroside and sulfate. In humans, arylsulfatase A is encoded by the ARSA gene.[5][6]

Clinical significance

A deficiency in Arylsulfatase A is associated with metachromatic leukodystrophy, an autosomal recessive disease.[7] Multiple sulfatase deficiency (MSD) is also associated with the ARSA gene.[8]

Biochemistry

Enzyme regulation

Arylsulfatase A is inhibited by phosphate, which forms a covalent bond with the active site 3-oxoalanine.[9]
