Aminopeptidase
What does aminopeptidase break down into?
Aminopeptidase breaks down macromolecular substrates into individual free amino acids, with small-molecule oligopeptides consisting of 2-3 amino acids remaining if hydrolysis is insufficient.

Mechanism of action
Aminopeptidase specifically binds to the N-terminus of polypeptide chains or proteins via its active site, sequentially hydrolyzes the terminal peptide bonds, gradually releases free amino acids, and ultimately degrades the substrate into individual amino acids.

Food Processing Field
Aminopeptidase catalyzes the hydrolysis of dairy products, meat products, and plant proteins to generate easily absorbable free amino acids and small-molecule peptides, enhancing the digestive utilization rate of products; it also precisely hydrolyzes bitter peptide segments in food while releasing umami amino acids, improving the taste and flavor of food.
Feed Additive Field
Aminopeptidase decomposes macromolecular proteins in feed, reduces the impact of anti-nutritional factors, promotes nutrient absorption in young animals, accelerates growth and development, enhances the immunity of farmed animals, and optimizes fur luster simultaneously.
Preparation of Bioactive Peptides
Experiments on soy protein isolate have confirmed that the dual-enzyme synergistic process (protease pretreatment combined with deep hydrolysis by aminopeptidase) increases the peptide content by 12% significantly compared with the traditional single protease hydrolysis method. Controlling protein enzymatic hydrolysis to obtain target bioactive peptides is a safe and efficient preparation approach.
Highly Specific Catalysis: Directionally hydrolyzes amino acid residues at the N-terminus of polypeptide chains, producing free amino acids or short peptides without side reactions.
Broad Substrate Adaptability: Compatible with various natural or synthetic polypeptides and protein hydrolysates, suitable for raw material processing needs in multiple industries such as food and feed.
Efficient Enzyme Activity Stability: Maintains high activity within a wide pH range (3.0-14.0) and temperature range (30-70℃), with salt tolerance and resistance to certain organic solvents.
Q1: Is aminopeptidase a proteolytic enzyme?
Yes, aminopeptidase is a proteolytic enzyme, an exopeptidase that hydrolyzes amino acid residues from proteins to produce free amino acids.
Q2: Where are aminopeptidases produced?
Aminopeptidases are mainly produced through three methods-microbial fermentation (the industrial mainstream), animal/plant extraction, and bioengineering synthesis-and Healthdream's aminopeptidase is manufactured via Aspergillus oryzae fermentation.
Q3: What is the function of aminopeptidase in digestion?
In the digestive process, aminopeptidase assists in the complete breakdown of proteins into small-molecule amino acids absorbable by the intestines, enhances protein digestion and absorption rates, and reduces the accumulation of incompletely digested peptides.
