I have a bit problem with the molecular modeling. I have a dímer (the two chains of this protein are the same sequence) and I want to put 34 residues at the N-terminal in each chain. I load my fasta (with this residues addition) in chimera and I blast a protein structure in the PDB that has the same residues as my protein without this addition. When I modeller (homology) my fasta, the programm only gives me one of the chain with this addition but I need the whole protein (with the two chains and with this residue addition for each chain as well). How  can I do it? I hope you resolve my problems. Thanks you for you attention.

Sincerely,

Víctor J. Gallardo
