PET degradation research

Protein engineering
for plastic circularity.

PET Lab develops computational methods for designing PET-degrading enzymes that remain active under industrial recycling conditions.

SCROLL

01 / The lab

We design PET-degrading enzymes for the conditions recycling actually requires.

PET Lab is a student-led research group focused on enzyme design for plastic recycling. We study how changes in protein sequence affect catalytic activity, stability, and performance under heat, pH, salt, and process-water constraints.

Our platform combines protein models with published experimental evidence. Every result is presented as a testable hypothesis—not a replacement for laboratory validation.

OPTIMIZATION TARGETS
Catalytic Activity Thermal Stability pH Tolerance PET Binding

Pick a known enzyme or paste your own sequence below

Simulate real-world recycling conditions. The AI optimizes for enzyme survival and performance under these parameters.

Target Temperature

Higher temp speeds up recycling but enzymes denature. Near the glass transition (70°C) PET chains loosen.

°C
PET glass transition — ideal for recycling
pH

Buffer pH affects charged residue stability and catalytic activity. Most PETases peak at pH 7.5–9.0 (Yoshida 2016; Tournier 2020).

pH
Slightly alkaline — optimal for most PETases
Ionic Strength (NaCl)

Salt concentration screens surface charge interactions via Debye-Hückel electrostatics. High ionic strength reduces the stabilising or destabilising effect of charged surface mutations. Industrial process water is typically 200–500 mM. (Tanford 1961; FoldX method)

mM
Physiological — standard lab buffer
Ca²⁺ Concentration (CaCl₂)

Calcium ions stabilise LCC, TfCut2, and Cut190 by coordinating conserved Asp/Glu residues at the N-terminal binding site. LCC: +14°C ΔTm at 2 mM Ca²⁺ (Kd=0.4 mM; Sulaiman 2012). TfCut2: +11°C at 5 mM (Kawai 2019). Mutations that alter chelating residues are penalised or rewarded accordingly.

mM
No Ca²⁺ — binding site correction inactive
Real-World Scenario

Select your operating environment. This determines which wet-lab validations are flagged on the results page. Chemical robustness is estimated from ESM-2 evolutionary fitness — not computed from contaminant data.

Controlled conditions — minimal validation needed beyond activity assay.

Each candidate is a unique enzyme variant the AI predicts will perform better.
