Summary
Researchers successfully intercalated proteins into montmorillonite clay, creating stable inorganic/organic nanohybrids. These materials maintain protein function and offer selective barriers, useful for protein therapeutics and tissue engineering.
Area of Science:
- Materials Science
- Biochemistry
- Nanotechnology
Background:
- Montmorillonite clays offer a layered structure suitable for hosting guest molecules.
- Intercalation of biomolecules into clays can alter material properties and functionalities.
- Controlling protein conformation and activity within inorganic matrices is crucial for bio-applications.
Purpose of the Study:
- To investigate the effective intercalation of protein molecules into montmorillonite galleries.
- To characterize the structural and functional properties of the resulting protein-clay nanohybrids.
- To explore the potential applications of these nanohybrids in protein therapeutics and tissue engineering.
Main Methods:
- Simple space enlarging and ion exchange processes for protein intercalation.
- Analysis of basal spacing changes in montmorillonite structure.
- Assessment of catalytic activity and biomacromolecule interaction barriers of nanohybrids.
Main Results:
- Proteins were effectively intercalated into montmorillonite, preserving native conformation and multilayered structure.
- Intercalation capacity exceeded Langmuir-type adsorption on external surfaces.
- Nanohybrids exhibited enhanced structural stability, preventing biomolecule exchange or clay exfoliation.
- Catalytic activity was preserved for small substrates, with a barrier established against large biomacromolecules.
Conclusions:
- Benign accommodation of proteins within inorganic platelets creates functional inorganic/organic nanohybrids.
- Nanoscaled manipulation of protein functions is achievable.
- These nanohybrids show promise for developing advanced protein therapeutics and tissue engineering scaffolds.

02:34Enzymes
Inside living organisms, enzymes act as catalysts for many biochemical reactions involved in cellular metabolism. The role of enzymes is to reduce the activation energies of biochemical reactions by forming complexes with its substrates. The lowering of activation energies favor an increase in the rates of biochemical reactions.

01:13Introduction to Mechanisms of Enzyme Catalysis
For many years, scientists thought that enzyme-substrate binding took place in a simple "lock-and-key" fashion. This model stated that the enzyme and substrate fit together perfectly in one instantaneous step. However, current research supports a more refined view scientists call induced fit. The induced-fit model expands upon the lock-and-key model by describing a more dynamic interaction between enzyme and substrate. As the enzyme and substrate come together, their interaction causes a mild...
01:30Enzyme Inhibition
Inhibitors are molecules that reduce enzyme activity by binding to the enzyme. In a normally functioning cell, enzymes are regulated by a variety of inhibitors. Drugs and other toxins can also inhibit enzymes. Some inhibitors bind to the enzyme’s active site, while others inhibit enzymatic activity by binding to other sites on the protein structure.
01:22Introduction to Enzymes
The use of enzymes by humans dates to 7000 BCE. Humans first used enzymes to ferment sugars and produce alcohol without knowing that this was an enzyme-catalyzed reaction. Wilhelm Kuhne coined the term 'enzyme' in 1877 from the Greek words ‘en’ meaning ‘in’ or ‘within’ and ‘zyme’ meaning ‘yeast.’
