How can I remove ligands in PDB structure?

Hello,

I have a question about comparing the structures of two proteins.

I tried to compare two proteins using superposing in expasy but there is a problem.

As you see, a structure from the official PDB file has RNA parts interacting with protein.

I just want to compare protein versus protein. Then, how can I remove that nucleotide parts?

Thanks!

Open PDB file in a text editor, and remove RNA coordinates.As I understand, protein viewers such as SPDBV allows you to hide the element of your choice. Check if the software you are using, allows you to hide intercalating RNA.

Thank you very much! I made images that I want using SPDBV. It really helps me.

If it's just one case, manually delete the ATOM/HETATM records you don't need from the PDB file.

Thank you! I could edit my PDB files using MS excel. And that RNA parts really removed!
