Help:Modify A PDB File

From Proteopedia

This page explains some ways to modify a PDB file in order to use it to show what you want to show.

Merging two (or more) PDB files

Often in Proteopedia, we want to show two or more models superimposed on each other. Currently, the best way to accomplish this in Proteopedia is to superimpose your structures using an external program (or by hand using a text-editing program), save your resulting multi-model or multi-chain PDB file, upload it into Proteopedia, and then load it in an applet or a scene on your Proteopedia page.

Using PyMOL

PyMOL makes it simple to superimpose two PDB files and save them as one PDB file, we just have to be careful to check the chain names
