Trypsin is an enzyme involved in the breakdown of many different proteins, primarily as part of digestion in humans and other animals such as monogastrics and young ruminants. Serpins – including trypsin inhibitors – are irreversible and suicide substrate-like inhibitors. [2] [3]
Many poisons produced by animals or plants are enzyme inhibitors that block the activity of crucial enzymes in prey or predators. Many drug molecules are enzyme inhibitors that inhibit an aberrant human enzyme or an enzyme critical for the survival of a pathogen such as a virus, bacterium or parasite.

About 200 Americans are killed per year by animals, according to one study, and the most common perpetrators may be surprising. A recent Washington Post analysis of government data between 2001 ...
Enzyme bioscavengers are being developed as a pretreatment to sequester highly toxic OPs before they can reach their physiological targets and prevent the toxic effects from occurring. Significant advances with cholinesterases (ChEs), specifically human serum BChE (HuBChE) have been made. HuBChe can offer a broad range of protection for nerve ...
The threat of so-called “mad cow disease” has all but faded from the collective memory, after its appearance in U.K. cattle in 1986. Human deaths from the scourge, caused by eating ...
