These scripts demonstrate the use of IMP, MODELLER and Chimera in the modeling of the bacterial molecular chaperone GroEL. First, MODELLER is used to generate structures for the individual components in the GroEL complex. Then, IMP is used to fit these components together into the electron microscopy density map of the entire complex.
A full description of the scripts can be found in Macromolecular assembly structures by comparative modeling and electron microscopy.
First, make a directory for the output by running
mkdir output. Output
files that were generated when these scripts were run for the first time are
also provided, in the
precalculate_results directory. Then, the scripts can
be run in order:
- Template identification:
- Template(s) selection by sequence:
- Density map segmentation:
- Template selection by fitting to a density map:
- Template alignment:
- Model building and assessment:
- Multiple fitting into a density map:
