File:2a7g.png Crystal Structure of Thermolysin 2a7g
Thermolysin (TML) is a thermostable metalloproteinase enzyme from Bacillus thermoproteolyticus . It catalyzes the hydrolysis of peptide bonds containing hydrophobic residues. The images at the left and at the right correspond to one representative Thermolysin (2a7g ). Thermolysin is a well researched metalloprotease containing zinc (click this!) and the amino acids His-Glu-X-His-His as its catalytic center. Glu-166, His-142 and -146 are grouped around the zinc atom , holding it fast, while Glu-143 holds the polarized water atom. Additionally, Tyr-157 and His-231 stabilize the substrate protein which will be cleaved into two smaller proteins.[ 1] [ 2] . See Metalloproteases and Matrix metalloproteinase for discussion.
