Summary
PepBuild is a web server for designing peptides and proteins with specific structures. It allows users to customize amino acid sequences, secondary structures, and add protecting groups, generating PDB files for further simulations.
Area of Science:
- Biochemistry
- Structural Biology
- Computational Biology
Background:
- Designing peptides and proteins with specific structures is crucial for understanding biological functions and developing therapeutics.
- Existing tools may lack flexibility in incorporating structural constraints and modifications.
Purpose of the Study:
- To introduce PepBuild, a user-friendly web server for de novo peptide and protein structure design.
- To enable the construction of peptides/proteins with defined secondary and tertiary structures, including terminal modifications.
Main Methods:
- Users select amino acid residues and specify secondary structure elements.
- Torsional angles can be manually inputted or optimized.
- The server incorporates N- and/or C-terminal protecting groups.
- Amino acid side chains are optimized using rotamer libraries.
Main Results:
- PepBuild facilitates the creation of custom peptide/protein structures.
- The server generates output files in Protein Data Bank (PDB) format.
- Designed structures can be directly used for molecular simulations or visualization.
Conclusions:
- PepBuild offers a valuable tool for researchers involved in peptide and protein design.
- The server simplifies the process of building structurally defined biomolecules.
- Generated PDB files are compatible with standard molecular modeling software.

Protein Digestion
Protein digestion begins in the stomach, where the highly acidic environment can easily disrupt protein structure by exposing the peptide bonds of polypeptide chains. After polypeptide chains are broken into individual amino acids by a series of digestive enzymes, the amino acids are transported to the liver via the bloodstream to produce energy.
Protein Organization
Overview
Protein Families
Protein families are groups of homologous proteins; that is, they have similarities in amino acid sequences and three-dimensional structures. Protein families usually occur because of gene duplication, where an additional copy of a gene is inserted into the genome of an organism. Mutations that change the amino acids but still allow the protein to be properly synthesized, will lead to new protein family members. If these new proteins contain similar amino acids in key locations, 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 Proteasome Structure
The ubiquitin-proteasome pathway is a well-known mechanism utilized by eukaryotic cells to remove cytoplasmic proteins that are misfolded, damaged, or no longer needed. In this pathway, the protein that needs to be eliminated undergoes a process called ubiquitination, where a chain of ubiquitin molecules is attached to the 48th lysine residue of the target protein. This ubiquitin modification helps the proteasome distinguish between a target protein and a healthy protein.
