Noncovalent Attractions in Biomolecules02:35

Noncovalent Attractions in Biomolecules

50.7K
Noncovalent attractions are associations within and between molecules that influence the shape and structural stability of complexes. These interactions differ from covalent bonding in that they do not involve sharing of electrons.
Four types of noncovalent interactions are hydrogen bonds, van der Waals forces, ionic bonds, and hydrophobic interactions.
Hydrogen bonding results from the electrostatic attraction of a hydrogen atom covalently bonded to a strong-electronegative atom like oxygen,...

Introduction to Mechanisms of Enzyme Catalysis

8.1K
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...

Intermolecular Forces03:13

Intermolecular Forces

58.3K
Atoms and molecules interact through bonds (or forces): intramolecular and intermolecular. The forces are electrostatic as they arise from interactions (attractive or repulsive) between charged species (permanent, partial, or temporary charges) and exist with varying strengths between ions, polar, nonpolar, and neutral molecules. The different types of intermolecular forces are ion–dipole, dipole–dipole, hydrogen bonds, and dispersion; among these, dipole–dipole, hydrogen...

Ligand Binding Sites02:40

Ligand Binding Sites

12.8K
Proteins are dynamic macromolecules that carry out a wide variety of essential processes; however, the activities of most proteins depend on their interactions with other molecules or ions, known as ligands.
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...

Enzymes

81.5K
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.
Enzyme deficiencies can often translate into life-threatening diseases. For example, a genetic abnormality resulting in the deficiency of the enzyme G6PD...

Induced-fit Model01:13

Induced-fit Model

80.8K
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.
Enzymes exhibit substrate specificity, meaning that they can only bind to certain substrates. This is mainly determined by the shape and chemical...

Area of Science:

  • Biochemistry
  • Structural Biology
  • Computational Biology

Background:

  • Enzymatic reactions rely on precise catalytic residues and an external force field generated by the protein body.
  • The protein's structure, often large, shapes this local force field, crucial for excluding water and ensuring reaction specificity.
  • Understanding the non-aqueous environment's role is vital for controlling highly specific enzymatic processes.

Purpose of the Study:

  • To comparatively analyze the force field diversity across different enzyme classes.
  • To investigate the influence of non-aqueous factors on protein structure and internal force fields.
  • To explore the potential of the fuzzy oil drop model for simulating protein folding in silico.

Main Methods:

  • Comparative analysis of selected enzymes from various classes.
  • Application of the fuzzy oil drop model (FOD) and its modified version (FOD-M).
  • Measurement of hydrophobicity distribution and its relation to the protein's force field.

Main Results:

  • Demonstrated diversity in force fields generated by different enzyme structures.
  • Quantified the impact of non-aqueous factors on shaping protein force fields.
  • The FOD model effectively characterizes the local environment influencing enzymatic activity.

Conclusions:

  • Enzyme structure dictates a specific force field essential for biocatalysis.
  • The fuzzy oil drop model provides insights into non-aqueous contributions to enzyme function.
  • This approach can enhance in silico protein folding simulations by modeling environmental influences.
