3D Viewer

View structures in-site—no redirect. Enter a PDB ID or pick a structure below (or enter SMILES to generate 3D). Rotate (drag), zoom (scroll), measure, export PNG/PDB, copy cite — all in the viewer bar and sidebar. Conformer preview

For small molecules: generate 3D from a SMILES string in the viewer, or load your own file in SDF Upload. Export coordinates (PDB, SDF when available) or a screenshot (PNG) from the viewer. For batch property reports use Batch SMILES; for format details see Export formats.

How to use the 3D viewer

Rotate & zoom: Drag to rotate the structure; scroll to zoom in/out.
Chains: Use the checkboxes in the viewer bar to show or hide each chain.
Display mode: Switch between cartoon, stick, line, or sphere in the viewer bar.
Seq ↔ 3D: In the right sidebar, open the panel to see residue numbers by chain; click a number to center the view. Hover in 3D to highlight the same residue in the panel.
Hover: Move the mouse over the structure to see residue info in the bottom-left overlay; the hovered residue is highlighted in red.
Measure: Turn on Measure in the bar, then click two atoms to see the distance (Å) and a red line.
Share: Use Copy link above to copy this structure’s URL. Export PNG, Download PDB, and Copy Cite are in the right-hand sidebar.
