Cell Biology

Chapter 4: Protein Structure and Function

Three-Dimensional Structure of Proteins

Introduction

• Proteins are the most diverse and functionally important macromolecules in cells
• They play crucial roles in nearly every aspect of cellular life

Protein Functions

• Enzymes are biological catalysts accelerating chemical reactions
• Structural proteins provide support and shape to cells and tissues
• Transport proteins carry small molecules across cell membranes
• Motor proteins generate movement in cells and tissues
• Antibodies recognize and neutralize foreign substances
• Hormones act as chemical messengers, transmitting signals
• Receptors receive and respond to environmental signals
• Transcription factors regulate gene expression

Protein Structure

• Proteins consist of amino acid chains
• An amino acid has a central alpha carbon bonded to an amino group (NH2)
• They also comprise a carboxyl group (COOH), a hydrogen atom, and a variable side chain (R group)
• The three-dimensional structure of a protein is critical for its function

Levels of Protein Structure

Primary Structure

• This is the linear sequence of amino acids linked by peptide bonds
• It determines the protein's structure and function

Secondary Structure

• This is the regular, repeating arrangement of the polypeptide chain in space
• Alpha helix (α-helix) features a helical coiling of the chain with intrachain hydrogen bonds
• Beta-pleated sheet (β-pleated) is the lateral alignment of chain segments with interchain hydrogen bonds

Tertiary Structure

• This is the overall three-dimensional folding of the polypeptide chain
• It is stabilized by interactions between amino acid side chains
  • Hydrophobic interactions occur
  • Hydrogen bonds form
  • Ionic bonds occur
  • Disulfide bridges form between cysteines

Quaternary Structure

• This is the association of two or more polypeptide chains (subunits) to form a functional protein complex
• Hemoglobin, with four subunits, is an example

Protein Folding

• Correct folding is crucial for protein function
• Chaperone proteins assist in proper folding and prevent incorrect aggregation

Protein Domains

• These are discrete functional and structural units within a protein
• Responsible for specific activities of a protein

Protein Denaturation

• This is the loss of a protein's native three-dimensional structure
• It is caused by factors like heat, extreme pH, or organic solvents
• Denaturation can result in the loss of biological function

Methods for Determining Protein Structure

• X-ray crystallography determines structure from X-ray diffraction patterns in protein crystals
• Nuclear Magnetic Resonance (NMR) determines structure in solution based on atomic magnetic properties

Proteomics

• This is the large-scale study of proteins, including their structure, function, and interactions

Conclusion

• The three-dimensional structure of proteins is crucial for their biological function
• Folding, domains, and interactions with other molecules determine a protein's activity
