Modelling at defined pH - for pmutscan - pH:mode not working

Category: 
Scoring
Loop Modeling
Chemically Modified Residues

Hi all, 

I am new to Rosetta and using various Rosetta protocols, primarily remodel and pmutscan, to assess the impact of various mutations on protein stability. I would like to model the protein and associated mutations at acidic pH as this may affect salt bridge formation and overall REU score.

simple_cycpep_predict thioether_lariat option

Category: 
Structure prediction

Hi all,

I'm trying to use simple_cycpep_predict with the option thioether_lariat for cyclization_type but seem to be running into a problem.  Based on what I read in the help docs, "thioether_lariat" should be an option that is possible, but when I tried to use it, I get:

ERROR: Illegal value specified for option -cyclic_peptide:cyclization_type : thioether_lariat

Is this an option that got removed and the help pages just weren't updated? Or am I missing something? I am attaching the the sequence that I am trying to model.

PyRosetta - PyMOL_Mover problem

Category: 
PyRosetta

I have Debian BUllseye installed on my Linux platform

I have installed pyrosetta 2022.09+release.433f0fc py39_0 and pymol-open-source 2.5.0  py39h20a8f2e_4 in a conda environment (Python-3.9.10).

I ma following the PyRosetta - PyMOL_Mover Tutorial and am having a strange problem.

Whew I paste 'cd /home/comp/Miniconda3/envs/PyRosetta/lib/python3.9/site-packages/pyrosetta' followed by 'run PyMOLPyRosettaServer.py' separately I get PyMOL <---> PyRosetta link started! (belwo)

    Hi, sorry for disturbing you but  I have problems about samll ligand docking in Ubuntu 20.04. It occurs errors when I followed jens Meiler's toturial about small ligand docking.

command line:

How does min_mover work?

Category: 
Structure prediction

I am using min_mover (lbfgs_armijo_nonmonotone) for minimizing the energy function of a protein for structure prediction in pyrosetta. 

In trying to get an energy plot over iterations, i set min_mover.max_iter(1) to 1. After each iteration of min_mover, I pause the optimization, store the current energy, and continue.

Rosetta Matcher not recognizing protonation forms of CST files like CYZ, HIS_D, etc

Category: 
Enzyme Design

Hi All,

I am using Rosetta 3.9 from the TACC for my Matcher run and want to use alternative protonation states of the amino acids I am working with, such as deprotonated cysteine CYZ or delta-Nitrogen-protonated histidine, His_D. Rosetta already has these residues defined in its database but Matcher can't recognize them at all. Does anyone know how I could approach this problem?

 

Thanks for the help in advance!
