Thermolysin is a well researched [[metalloproteases|metalloprotease]] containing <scene name='User:Ralf_Stephan/Sandbox_2/Zinc/2'>zinc</scene> (click this!) and the amino acids His-Glu-X-His-His as its catalytic center. <scene name='User:Ralf_Stephan/Sandbox_2/Res_yellow/3'>Glu-166, His-142 and -146 are grouped around the zinc atom</scene>, holding it fast, while <scene name='User:Ralf_Stephan/Sandbox_2/Res/1'>Glu-143 holds the polarized water atom.
