Hi, Sorry, I have noticed that someone already asked the following question two years ago and Azat Badretdinov had answered the it. But I still don't understand the meaning behind the STARTING_MODEL" and "ENDING_MODEL. > > > >What exactly is the meaning behind setting "STARTING_MODEL" and > >"ENDING_MODEL"? Does setting the former to 1 and the latter to, say, > >7 result in seven models being built with the 7th model being the most > >refined? >No, it does not. STARTING and ENDING will determine the range of indeces >in .B???? file names of the models I am modeling a very short peptide with modeller4. If I set STARTING_MODEL=1, ENDING_MODEL=10, I get 10 models which have different orientations and spatial location. If I would like to get a model which can overlap with the original model (maximum uses the template coordinates), how to do it? And is it possible to keep the backbone in the same conformation of original peptide ? All suggestions are highly appreciated. Thank you for your help. ****************************** Xiao-Ping Zhang Department of Biochemistry Arrhenius Laboratories of Natural Sciences Stockholm Universities 106 91 Stockholm Sweden Phone: 046-08-162472 /162582 Fax: 046-08-153679 e-mail: zhang@biokemi.su.se
Hi STARTING and ENDING model variables define how many models to generate. Because the structure optimization is stochastic (MD simulation) you can expect minor differences among different structures, especially if you have such regions in the structure which are not very well defined by restraints (segments with insertions, vicinity of deletions or loosely defined substrates relative to the template etc.). These variables also define the extension of your model files as it was noted by Azat: technically it is useful if you run modeling under different circumstances, e.g. generate 10 models with one ligand between 1-10, than generate 10 models using different ligand or templates (Starting MODEL=11, ENDING_MODEL=20) etc. > I am modeling a very short peptide with modeller4.

Dear Dr. Andras Fiser, Thank you for your suggestion. Yes, after I add SET FINAL_MALIGN3D = 1 in the top file, the final model is much close to the template, but still not superposed, but this is not the main problem. I also noticed that the backbone conformation of the model and the template is different. This is what I would like to overcome if possible. Probably I missed something in my top file if modeller can do this kind of work. Here is my top file. # Homology modelling by the MODELLER TOP routine 'model'. INCLUDE # Include the predefined TOP routines SET OUTPUT_CONTROL= 1 1 1 1 SET ALNFILE = 'peptide_1.ali' # alignment filename SET KNOWNS = '1dkxB' # codes of the templates SET SEQUENCE = 'peptide_1' # code of the target SET ATOM_FILES_DIRECTORY = './:../atom_files' # directories for input atom fileSET STARTING_MODEL= 1 # index of the first model SET ENDING_MODEL = 1 # index of the last model # (determines how many models to calculate) CALL ROUTINE = 'model' # do homology modelling SET FINAL_MALIGN3D = 1 And I also attached the model and template. Thank you for your time. Sincerely, Xiao-Ping Zhang Andras Fiser wrote: > Hi > > STARTING and ENDING model variables define how many models to generate.

Dear Dr. Zhang, I believe it is not necessarily a good idea to use modeller for a heptapeptide modeling based on another heptapeptide unless you are sure that they adopt a very similar conformation. I do not know what is your environment (is it a docked peptide on a protein surface, or is it in solvent etc.) but there is no guarantee that even the same heptapeptide will have the same conformation in different environments. Modeller relies on utilising the idea of evolution, that full size, sequentially similar proteins in physiological environment (for which modeller basically does not account for) adopt similar folds, while small peptides rely more on energetic criteria, which is not what modeller was designed for. Nevertheless: > I also noticed that the backbone conformation of the model and the template is > different. This is what I would like to overcome if possible. Probably I missed > something in my top file if modeller can do this kind of work. Here is my top > file. Modeller builds a model based on the given restraints derived from statistical observations of features from other proteins, from molecular mechanics forcefields and your template. These retrains will not necessarily guide the model to entirely the same conformation as the template. As i checked your model and template I would say that is pretty much what one would expect. As I mentioned above, in case of such a short fragment one is fairly lost, having no solid reference, and maybe way off reality. If you want to force modeling to deal only with sidechains and retain the same backbone conformation include in your top file: SUBROUTINE ROUTINE = 'select_atoms' PICK_ATOMS SELECTION_SEGMENT='@:@' 'X:X',; SELECTION_SEARCH='segment', PICK_ATOMS_SET=1, ; RES_TYPES='all', ATOM_TYPES='SDCH', ; SELECTION_FROM='all', SELECTION_STATUS='initialize' RETURN END_SUBROUTINE but I mention again that to my opinion it is an inadequate use of Modeller. I would prefer some detailed mol mechanics or semi empirical forcefields as CHARMM, AMBER or ECEPP, preferably with solvent representation and exhaustive optimisation method.
