I have an NMR structure of an oligomer which belongs to transmembrane
domain region. Also, I have the single extramembrane region (X-ray
crystal) of that TMDs. Now my question is how can I dock that
extramembrane part on that oligomer and ask the program to replicate it
to the same symmetry of the oligomer ! Can modeller do like that ?
Modeller can reproduce the structures of the individual proteins just
fine, but if you don't have interaction data it won't dock them
automatically - it is not a docking program. If you dock your two input
structures together and give them to Modeller as a single template with
two chains, it should do what you want.
