Chemical structure and physical properties of Nattokinase

Nattokinase is an enzyme derived from a traditional Japanese food called natto, which is made from fermented soybeans. The enzyme has gained attention due to its potential health benefits, particularly in promoting cardiovascular health. Here are some details about the chemical structure and physical properties of nattokinase:

Chemical Structure of Nattokinase:


Nattokinase is a serine protease, which means it belongs to the class of enzymes known as proteases that cleave peptide bonds in proteins. The specific amino acid sequence and structure of nattokinase are derived from the bacteria Bacillus subtilis during the fermentation of soybeans to produce natto.

The primary structure of nattokinase is a sequence of amino acids linked together by peptide bonds. Its chemical structure includes various amino acids, with the active site containing a serine residue essential for its proteolytic activity.

Physical Properties of Nattokinase:

Molecular Weight: The molecular weight of nattokinase is approximately 27-28 kDa (kilodaltons).

Optimal pH: Nattokinase exhibits enzymatic activity within a specific pH range. The optimal pH for its activity is typically in the range of 6.0 to 8.0.

Temperature Sensitivity: Enzyme activity is often influenced by temperature. Nattokinase is generally stable and active at a temperature range of 37-70 degrees Celsius.

Substrate Specificity: Nattokinase specifically acts on peptide bonds in proteins. Its substrate specificity and cleavage sites are related to its proteolytic activity.

Enzymatic Activity: Nattokinase is known for its fibrinolytic activity, meaning it can break down fibrin, a protein involved in blood clot formation. This property has led to research on its potential benefits for cardiovascular health.

It’s important to note that while there is some scientific evidence supporting the potential health benefits of nattokinase, further research is needed to fully understand its mechanisms and establish its efficacy for specific health conditions. As with any supplement or enzyme, individuals should consult with healthcare professionals before incorporating it into their routine, especially if they have pre-existing health conditions or are taking medications.

The pros and cons of Nattokinase

Nattokinase is an enzyme derived from the traditional Japanese food natto, which is fermented soybeans. It has gained attention for its potential health benefits, particularly in relation to cardiovascular health. However, it’s important to note that while some studies suggest positive effects, more research is needed to fully understand its efficacy and safety. Here are some potential pros and cons of nattokinase:

Pros of Nattokinase:

Cardiovascular Health: Some studies suggest that nattokinase may have a positive impact on cardiovascular health by promoting blood circulation and helping to dissolve blood clots. This could potentially reduce the risk of cardiovascular diseases.

Fibrinolytic Activity: Nattokinase has fibrinolytic properties, meaning it can break down fibrin, a protein involved in blood clot formation. This property may be beneficial in preventing or treating conditions related to excessive blood clotting.

Blood Pressure Regulation: Some research has indicated that nattokinase may contribute to the regulation of blood pressure by promoting blood vessel dilation and reducing blood viscosity.

Antioxidant Properties: Nattokinase may possess antioxidant properties, which could help neutralize free radicals and reduce oxidative stress in the body.

Cons of Nattokinase:

Limited Research: While some studies have suggested potential benefits, the research on nattokinase is still limited, and more high-quality, large-scale studies are needed to establish its efficacy and safety conclusively.

Interactions and Side Effects: Nattokinase may interact with blood-thinning medications, potentially increasing the risk of bleeding. Individuals taking anticoagulant drugs or those with bleeding disorders should consult their healthcare provider before using nattokinase. Side effects may include gastrointestinal discomfort in some individuals.

Quality and Safety: The quality of nattokinase supplements can vary, and there may be concerns about the purity and safety of some products. It’s crucial to choose reputable brands and consult with a healthcare professional before using any supplements.

Not Suitable for Everyone: People with soy allergies should avoid nattokinase supplements, as it is derived from fermented soybeans. Additionally, pregnant or breastfeeding women and individuals with certain medical conditions should consult their healthcare provider before using nattokinase.

In conclusion, while there is some promising research on the potential benefits of nattokinase, it is essential to approach it with caution. Individuals considering nattokinase supplementation should consult with a healthcare professional to assess its appropriateness for their specific health needs and circumstances.
