Episode notes
Tiny Active‑Site Change Drives Major Chemistry
- The identified OLADE enzyme (gene 1864) performs decarboxylation and oxidation in one step, preserving the tagged nitrogen.
- A single OH difference (tyrosine vs phenylalanine) in the active site controls substrate retention and the concerted reaction.
Engineer Yeast To Produce Alkaloids
- Use the one-step gene blueprint to port alkaloid biosynthesis into scalable hosts like yeast.
- Grow engineered yeast at industrial scale to cheaply produce securinine and related compounds.
Squeezing Beats The Standard Quantum Limit
- Squeezed quantum states reallocate uncertainty: reduce noise where you care and increase it where you don't.
- That lets measurements beat the standard quantum limit without violating Heisenberg.
