Protein promoting vibrations in enzyme catalysis--a conserved evolutionary motif
Journal of Proteome Research
|August 30, 2003
Summary
Researchers identified key amino acid residues in enzymes that promote vibration. A conserved sequence motif, the protein promoting vibration (PPV) generating sequence, was found across various alcohol dehydrogenases, indicating natural selection.
Area of Science:
- Biochemistry
- Computational Biology
- Enzymology
Background:
- A computational method was developed to identify critical residues involved in protein promoting vibration (PPV) in enzymes.
- This method was applied to horse liver alcohol dehydrogenase (HLADH), identifying eight significant residues.
Discussion:
- The identified residues form a conserved "PPV generating sequence" motif.
- This motif is unique and present in a broad range of alcohol dehydrogenases from various sources.
- This suggests evolutionary selection for this specific sequence.
Key Insights:
- Identified eight key residues in HLADH crucial for protein promoting vibration.
- Defined a novel "PPV generating sequence" motif.
- Demonstrated the evolutionary conservation and natural selection of this motif in alcohol dehydrogenases.
Outlook:
- Further investigation into the functional role of the PPV generating sequence in enzyme dynamics.
- Application of the computational method to other enzyme families to identify similar conserved motifs.
- Exploring the link between protein vibration and enzyme catalytic efficiency.

01:49Conserved Binding Sites
Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function.
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally analyses the...

01:13Enzymes and Activation Energy
The activation energy (or free energy of activation), abbreviated as Ea, is the small amount of energy input necessary for all chemical reactions to occur. During chemical reactions, certain chemical bonds break, and new ones form. For example, when a glucose molecule breaks down, bonds between the molecule's carbon atoms break. Since these are energy-storing bonds, they release energy when broken. However, the molecule must be somewhat contorted to get into a state that allows the bonds to...
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...

01:58Mechanical Protein Function
Proteins perform many mechanical functions in a cell. These proteins can be classified into two general categories- proteins that generate mechanical forces and proteins that are subjected to mechanical forces. Proteins providing mechanical support to the structure of the cell, such as keratin, are subjected to mechanical force, whereas proteins involved in cell movement and transport of molecules across cell membranes, such as an ion pump, are examples of generating mechanical force.
