We present experiments that show the inhibition of the catalytic activity of the enzyme urease on the chemical degradation of urea with copper ions. In addition, we demonstrate the efficiency of the antidotes 2,3-dimercapto-1-propanesulfonic acid (DMPS, 2,3-bis(sulfanyl)propane-1-sulfonic acid) and 2,5-dimercapto-1,3,4-thiadiazole (DMTD) on reactivation of urease by complexation of copper.
