[Chimera-users] Create a protein model using Chimera?

[Elaine Meng]

Dear Dr Maja Divjak,
Sorry, Chimera does not do de novo modeling.  Although the Chimera-Modeller interface does include untemplated loop-building, that is more appropriate for shorter missing segments within an existing protein, not entire domains or proteins.

I can only recommend you do some searching of web resources and perhaps literature, as I am sure there are many programs for that kind of modeling.  I have not done it myself, so I don't have any specific recommendations.  Other than that, you might try asking for recommendations of what program(s) to use on some more general forum such as the computational chemistry list, CCL.net :

I was therefore wondering what is the best approach to generating a 3d structure for the propeptide domain using the protein sequence and Chimera? If you could please outline a possible process, I would very much appreciate it. I see you have tutorials for comparative modeling, but in this case there is nothing to compare it to except other homologous sequences from the IL-1 family.
