LabCanvas Protein viewer: PDB structures in your browser

The LabCanvas Protein viewer shows 3D structures from the Protein Data Bank in the browser, powered by Miew. Load any PDB ID or your own PDB or mmCIF file; a link such as /protein.html?pdb=4HHB opens an entry directly.

Choose a representation, such as cartoon or ball-and-stick, and a colouring, add a transparent surface, and select residues on the sequence bar to give them their own style. Export the view as a PNG at 1×, 2× or 4× with a transparent background, or add it to a figure. It is a focused viewer for making clear structure images for papers, slides and teaching, not a molecular modelling package.
