[Chimera-users] Building protein-protein complex with known interacting residues

[Aldo Segura]

Dear Fei,

I think you might do that in Chimera, but it will be merely illustrative
because you don't know the correct orientation of the proteins into the
complex. I think you should go first for protein-protein docking program to
predict the orientations of the proteins into the complex. Moreover, you
can filter the docking predictions by keeping those that are according to
your experimental results and then, visualize the predicted complexes in
Chimera. For example, you can try with ClusPro server:

Best,

Aldo
