Good question, but once you think about it, the answer is quite simple. Protease needs to grab on to something (a protein) in order to digest it. It cannot grab onto itself. More specifically, proteases are designed to recognise specific proteins or protein sequences which they bind to and then cut or break up the protein at. The protease cannot turn around on itself in order to catalyse this reaction.

This answer isn't quite correct. In your answer you act as if there is only one pepsin molecule. If that was the case then indeed pepsin cannot 'grab onto itself'. However the question should have been : why doesn't pepsin digest other pepsin molecules. To find the answer to that you would have to look closer into what kind of atoms the molecules are made of and why they do not 'react' with eachother.

Enzyme that digest proteins?

Proteases are enzyme that digest proteins. In stomach we have proteases such as trypsin, pepsin and chymotrypsin that digest proteins. In addition there are peptidases that digest the peptides to simple amino acids.


Is protease an enzyme?

Yes, protease is an enzyme that breaks down proteins into smaller peptides or amino acids. It is involved in various cellular processes, including digestion, protein signaling, and recycling of damaged proteins.


Where on protease does a protein bond itself to?

It depends on the protease, but as with all enzymes, the substrate binds to the active site.


What is the name of the enzyme that will digest proteins into peptides?

The enzyme that digests proteins into peptides is called protease.

Can protease digest amino acid?

No, proteases digest proteins, producing protein fragments. The smallest fragment of a protein is an amino acid, the monomers from which the polymers we call proteins are built.


Name of the protein that can destroy protein?

Why would a person who is unable to produce the enzyme protease benefit from eating pineapple or pawpaw?

Pineapple and pawpaw contain enzymes called bromelain and papain, respectively, which can help digest proteins in the absence of protease. By consuming these fruits, individuals lacking protease may find improved digestion of protein-rich foods.


Are protease enzymes used in baby food?

* Trypsin (a serine protease) is used in baby food to pre-digest it. It can break down the protein molecules which helps the baby to digest it as its stomach is not strong enough to digest bigger protein molecules. See the Related Link.


A milk protein-digesting enzyme found in children?

It's not rennin... christ. Lactase is needed to digest the Lactose, Protease is needed to digest the casein and whey protein and Lipase is needed to digest the fats (lipids) in the milk.
