Hello!

Having obtained a satisfactory 3D model of my protein using Modeller with structures known in the PDB for three homologs, I would like to add a nucleic acid ligand (a tRNA).

None of the three PDB structures I used contained the nucleic acid, but I have other PDB files for one of the three homologs with the same nucleic acid.

In the PDB files for the known protein/nucleic acid complex, the coordinates for the nucleic acid are not under HETATM residues but simply as ATOMS after the protein coordinates.

What would be the simplest way to build a first quick model of my protein with the tRNA just to get an idea of the complex?

Thanks for any suggestions!
