Protein Folding

12.8K
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.
Protein Structure Is Critical to Its Biological Function
Proteins perform a wide range of biological functions such as catalyzing chemical reactions, providing...

Protein and Protein Structure

93.9K
Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective. They may serve in transport, storage, or membranes; or they may be toxins or enzymes. Their structures, like their functions, vary greatly. They are all, however, amino acid polymers arranged in a linear sequence.
A protein's shape is critical to its function. For example, an enzyme...

Protein Organization01:24

Protein Organization

10.2K
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....

Area of Science:

  • Structural biology
  • Bioinformatics

Background:

  • Polyproline helix type II (PPII) is a significant protein secondary structure.
  • PPII plays vital roles in biological macromolecule interactions.
  • PPII constitutes 3-10% of protein residues but is understudied.

Purpose of the Study:

  • To introduce the PolyprOnline database for PPII structure assignment and analysis.
  • To facilitate research on the structure and function of PPII.

Main Methods:

  • Development of a dedicated database for PPII analysis.
  • Assignment and analysis of PPII structures.

Main Results:

  • Most popular assignment tools do not identify PPII structures.
  • The PolyprOnline database provides a dedicated resource for PPII study.

Conclusions:

  • The PolyprOnline database addresses the gap in PPII structure analysis.
  • This resource will aid in understanding the functional roles of PPII.
