Function
Sulfatase-modifying factor (SUMF) is an enzyme that catalyzes the hydrolysis of sulfate esters by oxidizing posttranslationally a cysteine residue in its substrate Sulfatase active site to 3-oxoalanine (C-α-formylglycine) residue[1].
Disease
Mutations in SUMF1 cause multiple sulfatase deficiency - a lysosomal storage disorder. SUMF1 is associated with chronic obstructive pulmonary disease[2].
Structural highlights
The structure of SUMF1 complex with its substrate sulfatase terminal peptide CTPSR. SUMF1 active site contains 2 cysteine residues and mutating either of them to serine results in an inactive enzyme. Cys341 was found to be responsible for substrate binding and makes a Cys-Cys bond to the peptide cysteine residue. The peptide binds at the surface of SUMF1 in an extended conformation making numerous interactions with the protein[3].
