Product Description
Catechol-O-Methyltransferase Human Recombinant
Overview
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.
Biological Activity
Specific activity is greater than 10,000 pmol/min/ug, and is defined as the amount of enzyme that sulfate from PAPS to Nacetyl-D-glucosamine per minute at pH 7.5, at 37˚C.
