Protein Folding

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

Peptide Bonds

Peptide Bonds

A peptide bond covalently attaches amino acids through a dehydration reaction. One amino acid's carboxyl group and another amino acid's amino group combine, releasing a water molecule. The resulting bond is the peptide bond. The products that such linkages form are peptides. As more amino acids join this growing chain, the resulting chain is a polypeptide. Each polypeptide has a free amino group at one end. This end has the N-terminal, or the amino-terminal, and the other end has a free...

Protein Organization

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....

Intrinsically Disordered Proteins

Intrinsically Disordered Proteins

Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Background:

Thionamides have been known for two centuries, but their endothioxopeptide subfamily has gained attention only since the 1980s.
Endothioxopeptides are foldameric compounds based on biologically relevant building blocks, representing a rapidly emerging scientific interest.
Despite growing interest, the number of naturally occurring endothioxopeptides remains limited.

Purpose of the Study:

To review the advancements in synthetic methods for endothioxopeptides.
To outline the conformational consequences of incorporating thionamide groups into polypeptide chains.
To discuss the emerging class of endoselenoxopeptide congeners.

Main Methods:

Literature survey on synthetic methods for endothioxopeptides.
Analysis of conformational changes induced by thionamide incorporation in peptides.
Review of natural sources and synthetic approaches for endothioxopeptides and endoselenoxopeptides.

Main Results:

Significant progress has been made in synthetic methodologies for endothioxopeptides.
Incorporation of thionamide groups into polypeptide chains leads to specific conformational consequences.
