Carbohydrate Sulfotransferase 5 (CHST5) is a Golgi-embedded enzyme that is found in B cells, T cells and intestinal epithelium and is also mediates sulfation of keratan in cornea. CHST5 is a sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the transfer of sulfate to position 6 of non-reducing N-acetylglucosamine residues of keratan. CHST5 works on the non-reducing terminal GlcNAc of short andlong carbohydrate substrates that have poly-N-acetyllactosamine structures.
CHST5 Human produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 380 amino acids (27-395 a.a.) and having a molecular mass of 42.9kDa.
CHST5 is expressed with a 6 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.
