What if we could reprogram biology to eat the most indestructible plastic on Earth—and turn its toxic waste into the hardest mineral in the human body?
Polytetrafluoroethylene (PTFE / Teflon) and per- and polyfluoroalkyl substances (PFAS, or “forever chemicals”) owe their near-immortality to the Carbon–Fluorine ($\text{C–F}$) bond ($\Delta H^\circ \approx 485\text{–}540\text{ kJ/mol}$)—the strongest single covalent bond in organic chemistry. Worse still, even if an engineered enzyme succeeds in snapping $\text{C–F}$ bonds inside a bioreactor or a living microbiome, the liberated Fluoride ions ($\text{F}^-$) rapidly poison the host cells at concentrations above $100\text{ ppm}$, killing the culture before remediation can finish.
Over an eight-part research series, we built TeaFlon: an open-source, 12-layer synthetic biology compiler powered by pg_bio inside PostgreSQL 18. Today, we are releasing the complete TeaFlon Pan-Organism Atlas (7,338 proteins across 930 organisms), an interactive step-by-step 3D molecular machinery breakdown, 9 Golden Gate wet-lab plasmid cassettes, and the Top 5 Wet-Lab Protocols to physically prove the technology at the bench.

For Everyone: Why Is It So Hard to Remove Teflon & PFAS from Our Gut, Rivers, and Oceans?
Before diving into atomic coordinates and SQL queries, let’s step back and ask a simple question: Why can nature rot a fallen oak tree, digest a steak, and even eat crude oil spills—yet a microscopic fleck of Teflon (PTFE) or PFAS can survive for centuries in the Pacific Ocean or pass through the human gut untouched?
Every natural biological material—wood, fat, sugar, protein—is built from carbon chains wrapped in Hydrogen ($\text{C–H}$) or Oxygen ($\text{C–O}$) atoms. Over 3.8 billion years, microbes and digestive organs evolved millions of enzymes shaped specifically to grab those bonds and snap them apart.
In 1938, chemists accidentally created something evolution had never seen at scale: a carbon chain completely sheathed in Fluorine atoms ($\text{C–F}$).
The Three Physical Traps That Defeat Every Ordinary Filter and Microbe
All digestive enzymes live and swim in water. Teflon is both hydrophobic (hates water) and lipophobic (hates oil). When a normal enzyme in your gut or a river drifts near a PTFE microplastic particle, the surrounding water molecules refuse to let the enzyme get close—like trying to grab a greased bowling ball underwater. Without a specialized physical grapnel, 98% of enzymes never even touch the plastic.
Fluorine is the most electronegative element on the periodic table—an atomic electron-vacuum. It hugs the inner carbon spine so tightly ($485\text{–}540\text{ kJ/mol}$) that the fluorine atoms form an overlapping, negatively charged armor jacket. Stomach acid ($\text{pH } 1.5$), sunlight, and normal bacterial enzymes simply bounce off this shield.
Here is the catch-22 that stops synthetic biologists: suppose you do engineer an enzyme strong enough to rip Fluorine off Carbon. Every snapped bond releases a raw Fluoride ion ($\text{F}^-$). At just $100\text{–}150\text{ ppm}$, free fluoride shuts down cellular energy factories (enolase and ATP synthase), killing the beneficial microbe or damaging surrounding gut and river life!
Two Real-World Battlegrounds: Rivers & Oceans vs. The Human Gut
In rivers and oceans, PFAS and PTFE microplastics are diluted across trillions of gallons of moving water—or concentrated into toxic brines by reverse-osmosis filters that otherwise require $1,100\text{ }^\circ\text{C}$ incineration. How TeaFlon solves it: By immobilizing our Extremophile TeaFlon Swarm inside treatment cartridges or bioreactor beds, the Hydrophobin Hook grabs passing fluorocarbons out of the water stream, the Scissor snaps the $\text{C–F}$ bonds, and the Tooth-Builder immediately precipitates the fluoride with natural river/seawater Calcium ($\text{Ca}^{2+}$) into heavy, ruby-red Fluorapatite sand that sinks harmlessly to the bottom of the tank.
Through drinking water, cookware wear-particles, and food chains, over 98% of humans now carry detectable PFAS in their blood and gut. Inside the body, you cannot use harsh chemicals or high heat, and you can never allow free $\text{F}^-$ ions to leak into the bloodstream. How TeaFlon solves it: Because the Human Amelogenin tag (WPSTDKTKREEVD) is physically tethered to the enzyme just ångströms away from the catalytic exit tunnel, every single cleaved fluoride ion is instantaneously locked with dietary calcium and phosphate into an inert, microscopic grain of synthetic tooth enamel ($$\text{Ca}_5(\text{PO}_4)_3\text{F}$$) that cannot be absorbed by the gut wall and passes safely out of the body.
🔧 2. Deconstructing the Machine: Explore All 4 Molecular Parts in 3D
To defeat all three traps simultaneously, we couldn’t just use a single natural enzyme. We had to fuse four distinct evolutionary inventions into a coordinated molecular assembly line.

How do those four parts work together when fused into a single 418-amino-acid polypeptide chain (teaflon_trifusion_local.pdb)?
Using pg_bio’s spatial operators (residue_distance), we first discovered that the catalytic nucleophile (Asp104:OD2) sits only 22.02 Å from the N-terminus (Met1), but 32.75 Å from the C-terminus (Ser304) on the opposite face of the protein. By attaching our flexible GGGGSGGGGS linker to the C-terminus, we gave the catalytic jaws a full 32.75 Å of steric clearance:

- Wild-Type
Q1JU72Dehalogenase (No Hydrophobin Hook, Gray Dashed Curve): Because PTFE is superhydrophobic, the unanchored enzyme remains in bulk water and barely scratches the polymer surface, releasing only3.07 ppm [F⁻]after 48 hours. - TeaFlon v2 Mesophilic TriFusion (
Q1JU72 + P79073 + AMELX, Cyan Curve): The Class II Hydrophobin anchor boosts effective interfacial occupancy by48.8x. Free fluoride crosses98.57 ppmat Hour 6 and reaches149.97 ppm [F⁻](99.98%conversion) by Hour 48—while the C-terminalWPSTDKTKREEVDAmelogenin tag continuously sequesters that fluoride into3,980.6 mg/L(3.98 g/L) of insoluble Fluorapatite (\(\text{Ca}_5(\text{PO}_4)_3\text{F}\)) bioceramic (Biofilm Toxicity Risk: LOW — Safe). - Extremophile Swarm Chimera (

Computational proof—even across 12 multiomics layers and 7,338 proteins—is only the blueprint. Everything in the TeaFlon repository (including all 9 Golden Gate plasmid sequences in teaflon_multihost_plasmids.fasta) has been engineered so that wet-lab teams can validate each physical claim independently, cheaply, and with unambiguous pass/fail instrumentation:

- Continuous ISE Logging: Mix $10\,\mu\text{M}$ TeaFlon TriFusion (and heat-inactivated enzyme negative control) with substrate in $50\text{ mM}$ Tris-SO₄ ($\text{pH } 8.2$, $30\text{ }^\circ\text{C}$ for
Q1JU72or $75\text{–}85\text{ }^\circ\text{C}$ for theA1RTA7extremophile chimera), diluting $1:1$ in TISAB II buffer at hours0, 2, 6, 12, 24, 36, 48. - $^{19}\text{F}$-NMR Orthogonal Proof: Verify emergence of the inorganic fluoride singlet at $\delta \approx -119\text{ ppm}$ (relative to $\text{CFCl}_3$, with $\text{CF}_3\text{COONa}$ at $-75.6\text{ ppm}$ as internal standard) alongside attenuation of $-\text{CF}_2-$ peaks ($-120\text{ to }-126\text{ ppm}$).

Objective: Deploy the soil-bioremediation chassis P. putida KT2440 (TeaFlon_TriFusion_v2_p_putida_T7, 60.0% GC) and halophilic archaeon H. salinarum NRC-1 (TeaFlon_TriFusion_v2_h_salinarum_PFDA, 71.6% GC) co-expressing the fluoride-riboswitch-inducible carotenoid operon (GGPPS + PSY + PDS $\rightarrow$ W9DPJ6) so that successful PFAS mineralization turns the white Fluorapatite precipitate Ruby-Red.

crcBfluoride-sensing riboswitch upstream of thecrtE-crtB-crtI(GGPPS-PSY-PDS) lycopene cassette so that intracellular $\text{F}^-$ flux triggers lycopene biosynthesis simultaneously with extracellular Fluorapatite crystallization. - UV-Vis & Colorimetric Gate: Extract an aliquot of the mineralized ruby-red bioceramic pellet in acetone/hexane and verify the unmistakable 3-fingered Lycopene absorbance triplet at $\lambda_{\max} = 444\text{ nm},\ 472\text{ nm},\text{ and } 503\text{ nm}$ ($\text{CIE } a^* > +25$). Any field operator can verify PFAS destruction without a mass spectrometer simply by inspecting the ruby-red mineral sediment.
🚀 Reproduce the Entire 12-Layer Pipeline Locally
Every script, SQL migration, PDB structure, and multi-host plasmid FASTA discussed in this post is open-source and reproducible with a single command:
git clone https://github.com/jonatas/teaflon.git
cd teaflon
uv sync
uv run teaflon
Executing uv run teaflon runs all 11 pipeline stages and 8 verification test suites against PostgreSQL 18 + pg_bio, compiling the 418-aa TriFusion, auditing SafeLocus_B, scoring the 4 LC-MS/MS peptides, materializing the 7,338-protein Pan-Organism Atlas, exporting the 9 Golden Gate plasmids (teaflon_multihost_plasmids.fasta), and simulating the 48-hour ISE & Fluorapatite kinetic curves.
