Explore the fascinating world of biological macromolecules: iMolview lets you browse and view in 3D protein and DNA structures from Protein Data Bank, drug molecules from DrugBank, and small molecules from Pubchem. Search for drug names like 'ibuprofen' or 'gefitinib' in DrugBank, or proteins like 'insulin' or 'thyroid receptor' in PDB. Information associated with each molecule in these databases is also at your fingertips. Sync and view your own structure files via iTunes. Molecular view can be customized with a rich set of molecular representations (wires, balls-and-sticks, space filling, ribbon diagrams, molecular surfaces) and various coloring schemes. Select residues, atoms or chains and color or change their representations individually. Select 'neighbors' of a ligand or any other selection to identify interacting atoms or residues. Set 'inertia' to the maximum and let your molecule spin in 3D indefinitely. Save the current scene (viewpoint + representation) as a slide which can be easily accessed later. Save the whole molecular document with multiple slides. Load and contour electron density map

Verdict

The call

The clearest difference is price: Perse Visualizer at Free against iMolview's $0.99.
