One changed letter in a protein’s code can alter everything. New large-scale research maps how amino acid substitutions affect the amount of protein present in a cell.
Cells under stress temporarily halt protein production. That sounds like a useful defence. But researchers found that chronic activation of this system actually accelerates aging.
Your body is full of proteins that have been chemically modified by sugar — not because of what you eat, but because of basic metabolism.
Life on Earth uses twenty amino acids to build every protein in every living thing. Researchers wondered whether all twenty are truly necessary — and used artificial intelligence to find out.
A worm barely a millimeter long can sniff out bacteria enriched with a specific amino acid it cannot make itself.
Ribosomes are the molecular machines inside every cell that build proteins. They were long thought to work identically in everyone.
Every cell in your body is constantly building proteins — the molecules that do nearly everything. But exactly how that production is controlled has remained surprisingly murky.
Proteins are fragile. Heat, acid, mechanical stress — they deform and fall apart. But a new study shows how combining artificial intelligence with classical chemistry can produce a protein scaffold so robust…
