beta-aspartyl-peptidase activity
Definition
Target type: molecularfunction
Catalysis of the cleavage of a beta-linked aspartic residue from the N-terminus of a polypeptide. [EC:3.4.19.5]
Beta-aspartyl-peptidase activity is a catalytic activity that cleaves peptide bonds on the carboxyl side of aspartic acid residues within a protein or peptide. This activity is typically found in enzymes known as aspartyl proteases. Aspartyl proteases are characterized by the presence of two aspartic acid residues within their active site, which are essential for catalysis.
The mechanism of action involves a two-step process:
1. **Activation:** The substrate binds to the active site of the enzyme, where the two aspartic acid residues are positioned to interact with the peptide bond. One aspartic acid residue acts as a general acid catalyst, donating a proton to the carbonyl oxygen of the peptide bond. The other aspartic acid residue acts as a general base catalyst, accepting a proton from the amino group of the peptide bond. This activation step leads to the formation of a tetrahedral intermediate.
2. **Hydrolysis:** The tetrahedral intermediate is then hydrolyzed by the addition of a water molecule, which is facilitated by the general base catalytic activity of one aspartic acid residue. This results in the cleavage of the peptide bond and the release of two peptide fragments.
Aspartyl proteases play crucial roles in a wide range of biological processes, including protein processing, signal transduction, and immune response. For example, the enzyme renin, which is an aspartyl protease, plays a crucial role in the regulation of blood pressure by cleaving angiotensinogen to produce angiotensin I. Other notable examples include pepsin, a digestive enzyme, and HIV protease, which is essential for the replication of the HIV virus.
Aspartyl proteases are also important drug targets, and several inhibitors of these enzymes have been developed for the treatment of various diseases, such as hypertension, cancer, and viral infections.'
