Researchers use AI to design proteins that cut up other proteins
Summary
Researchers used artificial intelligence (AI) to design new proteins called proteases that can cut other proteins with high precision. These AI-designed enzymes were tested by breaking down proteins linked to neurological diseases.Key Facts
- Proteins are made of amino acids connected by strong peptide bonds.
- Peptide bonds are very stable and would last hundreds of years without enzymes.
- Organisms create enzymes called proteases to break these peptide bonds.
- Two types of natural proteases exist: zinc proteases and cysteine proteases, each with different chemical methods to cut proteins.
- Scientists used AI to mix and match parts of these proteases to create new enzymes.
- These new enzymes can be adjusted to cut specific protein targets.
- The researchers tested these enzymes on proteins related to brain diseases and showed they can cut them effectively.
- The study was conducted mainly by a team at the University of Washington led by Nobel laureate David Baker.
