Visual Peptide3D reaction demo
Multi-frame trajectory playback: each demo loads a sequence of PDB structures and plays them in order. Use Play/Pause and frame buttons to control playback.
Single structure viewer · Peptide Library
Using your own data
- By PDB IDs — One ID per frame, in order (e.g. binding pathway or key conformations). Loaded from RCSB.
- By file URL — A single PDB with multiple
MODEL … ENDMDLblocks (e.g. from MD or NMR). Use a path underpublic/or a full URL. - Morph (A→B) — Interpolate between two structures (same atom count). Good for teaching or simple transitions.
Preset demos
Pre-built examples to show playback. Click Play in each card. For real binding or MD trajectories, use the loader above with your own PDB IDs or multi-MODEL file.
Semaglutide & GLP-1 receptor
Key structures in GLP-1 signalling: peptide (PDB 6XBM) and GLP-1 receptor (PDB 7F9W). Conceptual two-frame view; replace with real binding trajectory for full reaction demo.
Frames: 6XBM → 7F9W (from RCSB PDB)
Small peptide structures
Two small peptide structures (2LL5, 1D4P) as a short trajectory. Illustrates multi-frame playback.
Frames: 2LL5 → 1D4P (from RCSB PDB)
Multi-MODEL PDB file (from public/)
Single file with multiple MODEL … ENDMDL blocks (e.g. from MD or NMR). To use your own: put the file in public/trajectories/ and use the loader above with By file URL.
File: /trajectories/demo.pdb (multi-MODEL PDB)
About this feature
Trajectories are pre-loaded or user-provided; no real-time simulation. Playback only.
How to prepare your own trajectory
- PDB IDs: List structures in time or pathway order; each ID = one frame (from RCSB).
- Multi-MODEL PDB: Export from MD/NMR software as one file with
MODEL 1 … ENDMDL MODEL 2 …; put inpublic/trajectories/or host elsewhere and use By file URL.
