Influence of polyelectrolyte polyallylamine (PAH) on structure and catalytic characteristics of urease (Canavalia ensiformis) by methods steady-state kinetics, fluorescence spectroscopy and circular dichroism is studied. It is shown that this polyelectrolyte is strong inhibitor of urease (50 % inhibition of enzyme with concentration PAH of 0,5 mkg/ml at neutral values рН). It is assumed regulatory role specific cation-binding sites on a molecule urease, defining structural dynamics a complex enzyme-polyelectrolyte.
