inhibitor of
thermolysin
Thermolysin (, ''Bacillus thermoproteolyticus neutral proteinase'', ''thermoase'', ''thermoase Y10'', ''TLN'') is a thermostable neutral metalloproteinase enzyme produced by the Gram-positive bacteria ''Bacillus thermoproteolyticus''. It requires ...
and is expected to inhibit other
metalloproteinase
A metalloproteinase, or metalloprotease, is any protease enzyme whose catalytic mechanism involves a metal. An example is ADAM12 which plays a significant role in the fusion of muscle cells during embryo development, in a process known as myo ...
