Sulfation in biochemistry is the enzyme-catalyzed addition of sulfate to another molecule. It often refers to a phase II enzyme reaction. This biotransformation process uses its cosubstrate 3`-phosphoadenosine-5`-phosphosulfate (PAPS) to transfer sulfate to a xenobiotic. Most of the time this is effective in rendering the xenobiotic less active .....
