THE CHEMISTRY

A shared intermediate, not a conveyor belt.

GOxGlucose + O₂ → lactone + H₂O₂
HRPH₂O₂ + 2 AH → 2 H₂O + 2 A•

AH is an electron donor. The lactone subsequently hydrolyzes; that downstream step is omitted. H₂O₂ diffuses between enzymes and can also escape.

LIVE MODEL OBSERVATIONS

0GOx turnovers
0HRP turnovers
—free HRP control

Brownian motion is paused until you start or select a mechanism.

Illustrative reaction events. No measured speedup, fitted kinetics, or physical time calibration.

A MODEL YOU CAN AUDIT

Know what each layer means.

EXPERIMENTAL COORDINATES

PDB heavy-atom positions; hydrogens and crystallographic waters omitted. Frozen internal coordinates, not a dynamic structure determination.

ILLUSTRATIVE DYNAMICS

Seeded Brownian diffusion and a precomputed harmonic-tether trajectory. Arbitrary model time; no MD or QM/MM calculation.

DESIGNED INTEGRATION

Membrane, full origami layout, attachment sites and strand-switch motion are design illustrations, not one experimentally validated cell.

Model limits, representations and reproducibility

GOx is shown using the deposited protomer reference, not a reconstructed native dimer. HRP uses chain A. The OmpF trimer uses assembly coordinates; its membrane placement is illustrative. The 1BNA duplex is an isolated crystal reference, not the sequence of the designed origami. Atom radii use van der Waals-like display sizes. Bond sticks in the heme view are inferred by distance and do not encode bond order.

The full scaffold is a designed 16-helix array (0.34 nm rise/base pair; 10.5 base pairs/turn; 2.5 nm axis spacing). Crossovers and linkers are illustrative, without staple-sequence routing or steric optimization. The illustrative transport mask uses a geometric opening, not an OmpF free-energy profile or a universal molecular-weight cutoff.

GOx requires an O₂ co-substrate and HRP requires two donor equivalents in the reaction-event model. Water is treated as implicit solvent. Atomic views never show scripted ligand docking as experimentally observed motion. Consult README, model metadata, and coordinate provenance.
