5 Best Free PDB Editor Software for Windows
Here is a list of best free PDB editor software for Windows. These are basically molecular modeling software which let you edit Protein Data Bank (PDB) files which contain 3D molecular structures. You can directly add/ remove hydrogen atoms, insert various chemical elements from the periodic table, define bonds, add nanostructures, transform molecular structure, etc. These software also provide inbuilt database from where you can directly insert various molecules, DNA, amino acids, different functional groups, etc. All in all, you get all essential tools in these software to easily edit PDB files.
Apart from PDB, you can also use the listed software to edit molecular files including XYZ, MOL, MOL2, etc. These software also provide a great molecule visualization environment to view molecular structures in 3D. You get handy rotate, pan, zoom, draw style, auto-rotate, and more features which help you properly view a PDB or any other supported chemical file.
In many of these PDB file editors, you get analysis and calculation features to estimate various parameters related to a molecule structure. These parameters include optimized geometry, energy, bond length, dipole moment, quadrupole moment, etc. In general, these are quite feature-rich software which can also be used to edit PDB file.
