RESEARCH: PROTEIN-BRUSH-POLYMER-SIMULATION
FOLDING PROJECT #12116 PROFILE

Peptides are great medicine but get broken down easily. This project looks at 'protein brush polymers' which protect peptides and help them reach their target. They'll study a specific peptide called Trpzip2 to see how its shape affects how the polymer works.

Protein Brush Polymers Short peptides are considered ideal therapeutics because of their small size and bioactivity, however they are prone to enzyme degradation.

Protein Brush Polymers allow peptides to bind to a hydrophobic backbone in a polymeric scheme which enhances the penetration of these peptides in cell/targets. In this project we simulate Trpzip2, which is a beta-hairpin peptide, for investigation of beta-sheet secondary structure effect on the polymer conformation. We have two broad aims in this study.

To simulate the peptide monomer as well as simulate a 15-mer polymer system with different configurations to investigate beta-sheet content.

Protein

Large biomolecules essential for structure, function and regulation of living organisms.

Proteins are complex molecules found in all living things. They perform a wide range of functions, including building and repairing tissues, transporting substances, catalyzing chemical reactions, and defending the body against disease.

Peptide

Short chains of amino acids linked together.

Peptides are short chains of amino acids, the building blocks of proteins. They can have various biological functions, such as acting as hormones, neurotransmitters, or antibiotics.

Polymer

Large molecules composed of repeating structural units (monomers).

Polymers are large molecules made up of many smaller repeating units called monomers. They have a wide range of applications, including plastics, textiles, and adhesives.

Trpzip2

A beta-hairpin peptide used in protein folding studies.

Trpzip2 is a short protein sequence known to form a specific structure called a beta-hairpin. It is commonly used in research to study how proteins fold and interact.

Beta-sheet

A common secondary structure in proteins characterized by hydrogen bonding between adjacent strands.

Beta-sheets are a type of protein structure where multiple protein strands run parallel or antiparallel to each other, forming a sheet-like arrangement. These sheets are stabilized by hydrogen bonds between the strands.

Monomer

A single unit that can be linked to others to form a polymer.

A monomer is a small molecule that can bind to other identical molecules to create a larger chain or network. Think of it like building blocks for polymers.
