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 (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].
