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 (click this!) and the amino acids His-Glu-X-His-His as its catalytic center. , holding it fast, while stabilize the substrate protein which will be cleaved into two smaller proteins.[1][2]. See Metalloproteases and Matrix metalloproteinase for discussion.
