Peptide bonds represent a cornerstone in molecular biology. They act as essential chemical linkages that bind amino acids into complex chains, ultimately forming peptides and proteins. These ...

Proteins are the end products of the decoding process that starts with the information in cellular DNA. As workhorses of the cell, proteins compose structural and motor elements in the cell, and they ...

A paper titled "Functional implications of unusual NOS and SONOS covalent linkages found in proteins," by Matthew D. Lloyd, Kyle S. Gregory, and K. Ravi Acharya, from the University of Bath Department ...

Cysteine’s thiol chemistry makes it central to forming disulfide bonds that lock peptides into stable, functional shapes. By combining careful placement of cysteine residues with selective protection ...

Proteins can form “catch-bonds” that tighten under force, much like a finger trap. Using artificial intelligence and molecular simulations, Auburn scientists uncovered how these bonds strengthen ...

AI analysis uncovers why certain protein interactions behave like a finger trap, gripping tighter the harder they’re pulled. Imagine tugging on a Chinese finger trap. The harder you pull, the tighter ...

Imagine tugging on a Chinese finger trap. The harder you pull, the tighter it grips. This counterintuitive behavior also exists in biology. Certain protein complexes can form catch-bonds, tightening ...
