aspartic-type endopeptidase activity
Definition
Target type: molecularfunction
Catalysis of the hydrolysis of internal, alpha-peptide bonds in a polypeptide chain by a mechanism in which a water molecule bound by the side chains of aspartic residues at the active center acts as a nucleophile. [ISBN:0198506732]
Aspartic-type endopeptidase activity refers to the catalytic hydrolysis of peptide bonds within a protein chain, specifically by enzymes that utilize an aspartate residue in their active site. These enzymes are characterized by their unique mechanism, which involves two aspartate residues that act in concert to facilitate the cleavage reaction.
One aspartate residue acts as a general acid, donating a proton to the carbonyl oxygen of the peptide bond. This protonation weakens the bond and makes it more susceptible to nucleophilic attack. The other aspartate residue acts as a general base, abstracting a proton from a water molecule. This generates a hydroxide ion, which then attacks the carbonyl carbon of the peptide bond.
The nucleophilic attack of the hydroxide ion results in the formation of a tetrahedral intermediate. This intermediate is unstable and quickly collapses, leading to the cleavage of the peptide bond and the release of the two peptide fragments.
Aspartic-type endopeptidases are found in a wide variety of organisms, including bacteria, archaea, eukaryotes, and viruses. They play essential roles in a variety of cellular processes, including protein processing, degradation, and signal transduction. Some well-known examples of aspartic-type endopeptidases include pepsin, chymosin, and renin. These enzymes are involved in the digestion of proteins in the stomach and are also important in the regulation of blood pressure.'
