Arylsulfatase A
Introduction
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.[1][2]
Pathology
Pathology
A deficiency is associated with metachromatic leukodystrophy, an autosomal recessive disease.[3]
Biochemistry
Biochemistry
Enzyme regulation
Arylsulfatase A is inhibited by phosphate, which forms a covalent bond with the active site 3-oxoalanine.[4]
