Summary
Enzyme stability is maintained in dense suspensions due to protein interactions and self-generated mechanical fluctuations. These factors preserve enzyme structure and catalytic activity over extended periods.
Area of Science:
- Biophysics
- Biochemistry
- Enzymology
Background:
- Proteins function in dynamic environments, with interactions and fluctuations impacting structure and activity.
- Enzyme stability is crucial for fundamental biological understanding and practical applications.
Purpose of the Study:
- Investigate the role of protein-protein interactions in enzyme conformational dynamics.
- Examine the impact of non-thermal active fluctuations on enzyme catalytic activity and stability.
Main Methods:
- Studied enzymes in dense suspension to observe structural integrity and catalytic function.
- Analyzed mechanical fluctuations generated by enzyme catalytic reactions.
Main Results:
- Enzyme catalytic activity and structural integrity were preserved in dense suspensions.

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...

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.

Most chemical reactions in cells require enzymes—biological catalysts that speed up the reaction without being consumed or permanently changed. They reduce the activation energy needed to convert the reactants into products. Enzymes are proteins, that usually work by binding to a substrate—a reactant molecule that they act upon.

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.’

01:19Turnover Number and Catalytic Efficiency
10.7K
The turnover number of an enzyme is the maximum number of substrate molecules it can transform per unit time. Turnover numbers for most enzymes range from 1 to 1000 molecules per second. Catalase has the known highest turnover number, capable of converting up to 2.8×106 molecules of hydrogen peroxide into water and oxygen per second. Lysozyme has the lowest known turnover number of half a molecule per second.

01:07Catalytically Perfect Enzymes
4.1K
The theory of catalytically perfect enzymes was first proposed by W.J. Albery and J. R. Knowles in 1976. These enzymes catalyze biochemical reactions at high-speed. Their catalytic efficiency values range from 108-109 M-1s-1. These enzymes are also called 'diffusion-controlled' as the only rate-limiting step in the catalysis is that of the substrate diffusion into the active site. Examples include triose phosphate isomerase, fumarase, and superoxide dismutase.
