HELP - Modeling the binding site in presence of ligands
Hi,
I am having issues reproducing the Advanced Tutorial provided at https://salilab.org/modeller/tutorial/advanced.html
I could not figure out how to write/fix a script to align the 1emd_bs.pdb template with the TvLDH model previously obtained. I have searched in the manual and I could not find how to generate a python script that will give the right alignment. My input files and script used are shown below:

An alignment is just a text file, so you can create it using Modeller's alignment functions, some other alignment program, or even by hand in a text editor. I believe that for this particular alignment it was indeed made manually. The sequence identity is so high that it's easy to align visually.

This won't work because Modeller alignments by default are global. Since 1emd is so much shorter than TvLDH, it will add a lot of huge gaps to try to stretch the sequence out to match. You would want to ask for a local alignment instead.
