Dear Gromacs Users,
I want to do some simulations of the protein (its N anc C terminals)
which crystal structure does not exist. I submitted the sequence to
www.proteinmodelportal.org <http://www.proteinmodelportal.org/>
obtaining different structures based on different proteins from Protein
Data Bank. For instance my N terminal has 180 aa. Obtained models covers
%Seq id of 78% for 36 residues, 68% for 36 different residues, 62% of 36
another residues and many other models below 50%. The website provides
you with the PDB files of your query so sounds perfect as you do not
have to mutate every residue one by one.
The question is whether this is efficent and provide a good result to
use such protein in my simualtions? Is this app. too big?
What are the other ways to overcome this problem (obtain structure of
the protein which crystal structure does not exist?
Homology modeling is a field unto itself. There are many programs that produce
results with varying accuracy. A quick look through some of the documentation
from that site suggests there should be good feedback about the quality of the
model.
There are probably other forums better suited to these types of discussions.
This mailing list is intended for Gromacs-related issues and usage. Please bear
that in mind.
