Interactive 3D viewers — TYMS / dUMP / 1HVY

All viewers are powered by 3Dmol.js. Each PDB file is embedded inline (no external loading), so these pages work both locally and via GitHub Pages. Drag to rotate, scroll to zoom, right-drag to translate. Receptor is shown as cartoon (spectrum-coloured), active-site residues as sticks, dUMP substrate in magenta, and (where present) raltitrexed cofactor in cyan.

Conditions: apo = receptor with cofactor pocket emptied (raltitrexed removed); holo = raltitrexed retained in chain A. Both runs use the dimer receptor (chains A + B) and identical Vina box & seed.
