Unsolved

Hi, when trying to relax a protein, I got the error message:

ERROR: unknown atom_name: 'CZH'  in residue TRP
 

However, there was no atom with the name 'CZH' in that pdb, not in TRP or any other residue.

The problem turned out to be the following block:

Dear all,

I have just started out my work in a computational protein design lab.
The first algorithm I learned at the beginning was backrub, which I know basically could be used for flexible backbone design.
After using it for a while, I have some doubt in my mind.
Would you mind sharing your valuable experience on the following situations regarding backrub?

1) I have generated 50k structures by backrub.
After removing redundant sequences, the number of unique amino acid sequence was just 1k.

Hello, I am using the following protocol, modified from the design raf-rac interface demo, to design a protien protein interface. I ran 2 designs in parallel using nstruct = 1,000 and ran SequenceProfile.py to analyze and found that the results were the same for each. Therefore I wondering exactly how the sequence space is "randomly" searched to identify mutations and how likely these mutations will be to give a more favorable interface in vitro. Thanks in advance

Hi There,

Myself Haresh, I am postdoctoral fellow at University of Toronto. I used PyRosetta for protein protein docking and working good. Usually rosetta did protein protein doking between only two proteins. Is there any avaiblity or options to do protein-protein docking with bound ligand with each protein(e.g. Protein-Ligand --- Ligand-Protein)? Thanks in advance for your help.

Looking forward to hear from you.
