Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Hydrolyzes cerebroside sulfate.

Miscellaneous

The metal cofactor was first identified as magnesium ion, based on the structure of the recombinant protein, but when purified from human placenta, the protein contains 1 calcium ion per subunit.

Catalytic activityi

A cerebroside 3-sulfate + H2O = a cerebroside + sulfate.

Cofactori

Ca2+1 PublicationNote: Binds 1 Ca2+ ion per subunit.1 Publication

Enzyme regulationi

Inhibited by phosphate. The phosphate forms a covalent bond with the active site 3-oxoalanine.1 Publication

Involvement in diseasei

Leukodystrophy metachromatic (MLD)41 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA leukodystrophy due to a lysosomal storage defect. Characterized by intralysosomal storage of cerebroside-3-sulfate in neural and non-neural tissues, with a diffuse loss of myelin in the central nervous system. Progressive demyelination causes a variety of neurological symptoms, including gait disturbances, ataxias, optical atrophy, dementia, seizures, and spastic tetraparesis. Three forms of the disease can be distinguished according to the age at onset: late-infantile, juvenile and adult.

Multiple sulfatase deficiency (MSD)1 Publication
The protein represented in this entry is involved in disease pathogenesis. Arylsulfatase A activity is impaired in multiple sulfatase deficiency due to mutations in SUMF1 (PubMed:15146462). SUMF1 mutations result in defective post-translational modification of ARSA at residue Cys-69 that is not converted to 3-oxoalanine (PubMed:7628016).2 Publications
Disease descriptionA clinically and biochemically heterogeneous disorder caused by the simultaneous impairment of all sulfatases, due to defective post-translational modification and activation. It combines features of individual sulfatase deficiencies such as metachromatic leukodystrophy, mucopolysaccharidosis, chondrodysplasia punctata, hydrocephalus, ichthyosis, neurologic deterioration and developmental delay.

Post-translational modificationi

The conversion to 3-oxoalanine (also known as C-formylglycine, FGly), of a serine or cysteine residue in prokaryotes and of a cysteine residue in eukaryotes, is critical for catalytic activity. This post-translational modification is severely defective in multiple sulfatase deficiency (MSD).1 Publication
