ARSA Human, SF9

Source: Sf9, Baculovirus cells.Sterile Filtered clear solution.The enzyme Arylsulfatase A, also known as cerebroside-sulfatase, is responsible to break down sulfatides. The main molecule that Arylsulfatase A breaks down is cerebroside 3-sulfate into cerebroside and sulfate. The enzyme is encoded by the ARSA gene in humans. Phosphate can form a covalent bond with the Arylsulfatase Aâ€TMs active site 3-oxoalanine, thus, inhibits the protein.ARSA produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 498 amino acids (21-509a.a.) and having a molecular mass of 53.0kDa. (Molecular size on SDS-PAGE will appear at approximately 50-70kDa) . ARSA is expressed with a 9 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.
