== Function == | |||
[[Thermolysin]] or '''thermostable neutral proteinase''' (TML) is a thermostable metalloproteinase enzyme from ''Bacillus thermoproteolyticus''. It catalyzes the hydrolysis of peptide bonds containing hydrophobic residues. See [[Metalloproteases]] and [[Matrix metalloproteinase]] for discussion. | |||
== Structural highlights == | |||
Thermolysin is a well researched 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. Additionally, Tyr-157 and His-231</scene> stabilize the substrate protein which will be cleaved into two smaller proteins.<ref>Matthews, BW.
