  The protease may be mercapto protease, preferably papain.

  The principle is that silver ion can inhibit the activity of free mercapto protease and thus inhibit its biological function [[4], [5], [6]].

  Considering that papain is a mercapto protease enzyme, and sulfydryl groups of papain are deemed to show a strong affinity for Au and Ag (as was the case for BSA).

  The cysteine protease inhibitor E-64 had little effect on enzyme activity, indicating that the HypZn active site does not contain cysteine and that it is not a mercaptoprotease.
