Summary
The hydrophobic force, crucial for protein folding, was initially overlooked despite early proposals. Its significance in polypeptide chain folding was recognized decades later, impacting protein science.
Area of Science:
- Biochemistry
- Molecular Biology
- Physical Chemistry
Background:
- The hydrophobic force is widely accepted as the primary driver for polypeptide chain folding into globular structures.
- Early recognition of hydrophobicity's role in protein folding by Langmuir and Bernal in 1938 was overshadowed by the competing "cyclol hypothesis."
Observation:
- The hydrophobic principle gained prominence in protein science following a 1959 review by W. Kauzmann.
- A theoretical paper by Frank and Evans (1945) provided a conceptual framework for understanding the origins of hydrophobicity in water structure.
Findings:
- Hydrophobic interactions are now accepted as the primary energetic driver for the folding of polypeptide chains into compact globular proteins.
- The acceptance of hydrophobicity as a key factor in protein folding was significantly influenced by theoretical work on water structure.
Implications:
- Understanding hydrophobic forces is essential for deciphering protein structure and function.
- This principle underpins research in drug design, protein engineering, and understanding diseases related to protein misfolding.

Overview
Noncovalent Attractions in Biomolecules
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,...

Conserved 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...

Molecular Chaperones and Protein Folding
The native conformation of a protein is formed by interactions between the side chains of its constituent amino acids. When the amino acids cannot form these interactions, the protein cannot fold by itself and needs chaperones. Notably, chaperones do not relay any additional information required for the folding of polypeptides; the native conformation of a protein is determined solely by its amino acid sequence. Chaperones catalyze protein folding without being a part of the folded protein.

Protein Organization
Proteins are polymers of amino acid residues. They are versatile and responsible for different cellular functions, including DNA replication, molecular transport, catalysis, and structural support. Proteins have a hierarchical structure comprising at least three levels of organization: primary, secondary, and tertiary structure. Some large proteins have a quaternary structure where individual protein subunits are linked together.
The primary structure of a protein is its amino acid sequence.
The primary structure of a protein is its amino acid sequence.
Protein Folding
Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.
