What is the difference between proteinase and peptidase?

Definitions

proteinase

- Referring to an enzyme that breaks down proteins into smaller peptides or amino acids.

- Talking about a type of proteolytic enzyme that is involved in protein digestion and metabolism.

- Describing a group of enzymes that hydrolyze peptide bonds in proteins.

peptidase

- Referring to an enzyme that breaks down peptides into smaller amino acids.

- Talking about a type of hydrolase enzyme that catalyzes the cleavage of peptide bonds.

- Describing a group of enzymes that are involved in the digestion and metabolism of proteins and peptides.

List of Similarities

• 1. Both are types of enzymes that break down proteins and peptides.
• 2. Both are involved in the digestion and metabolism of proteins.
• 3. Both catalyze the hydrolysis of peptide bonds.
• 4. Both are essential for the proper functioning of the human body.
• 5. Both are used in various industrial and biotechnological applications.

What is the difference?

• 1. Substrate specificity: Proteinases specifically target proteins, while peptidases target peptides.
• 2. Cleavage site: Proteinases cleave peptide bonds at specific sites within the protein molecule, while peptidases cleave peptide bonds between specific amino acids.
• 3. Function: Proteinases are involved in the breakdown of larger proteins into smaller peptides, while peptidases break down peptides into individual amino acids.
• 4. Classification: Proteinases are classified based on their mechanism of action, while peptidases are classified based on their substrate specificity.
• 5. Examples: Proteinases include trypsin, chymotrypsin, and pepsin, while peptidases include aminopeptidases, carboxypeptidases, and dipeptidases.

📌

Remember this!

Proteinase and peptidase are both types of enzymes that are involved in the digestion and metabolism of proteins. However, the difference between them lies in their substrate specificity, cleavage site, and function. Proteinases specifically target proteins and cleave peptide bonds at specific sites within the protein molecule, while peptidases target peptides and cleave peptide bonds between specific amino acids to break them down into individual amino acids.
