I am a person using Chimera to adding missing residues to a protein from Protein Data Bank. My protein has 2 chains: A and B which both have missing residues. I have used Chimera tools compliment with Modeller to adding missing residues in both chain. The problem is I want to save the whole protein which consists of 2 fixed chains, however when I saved with PDB it only show 1 chain. How can I do that? 

I am looking forward for your replying.

Thank you.

Best regards,

Khai.
