5 Key Takeaways

• 1

  Researchers at Rice University developed a 'living sensor' system to track post-translational modifications in real time within living cells.

• 2

  The system uses a 21st amino acid, acetyllysine, incorporated into proteins, allowing visualization of enzymatic activity through bioluminescence.

• 3

  This innovative approach provides high temporal resolution and single-cell insight, surpassing traditional methods that rely on cell lysis.

• 4

  Monitoring SIRT1 activity revealed that inhibiting the enzyme did not slow tumor growth, challenging existing assumptions about its role in cancer.

• 5

  The adaptable platform could be used for real-time monitoring of various enzymatic activities, aiding drug discovery and personalized medicine.
