TIL: AlphaFold solved the 50-year protein folding problem - predicting 3D protein structure from amino acid sequence. AlphaFold 3 now predicts interactions between proteins, DNA, RNA, and small molecules. This accelerates drug discovery by orders of magnitude, predicting binding sites computationally.


```python
# AlphaFold-style structure prediction workflow
sequence = 'MVLSPADKTNVKAAWGKVGAHAGEYGAEALERMF...'

# Model predicts 3D coordinates for each atom
predicted_structure = alphafold.predict(sequence)

# Output: atom positions, confidence scores, binding sites
# Previously took months in lab -> now seconds on GPU
```
