PyRosetta

I am trying to use IntearctiveRosetta on windows 10 environment and have zero knowledge about coding.....could anyone help me to solve this error......which comes up when I do a position scan using IntearctiveRosetta.....

Traceback (most recent call last):File "scripts\daemon.py", line 2024, in daemonLoopdoPMutScan()File "scripts\daemon.py", line 503, in doPMutScanos.rename("scanprogress", "scanoutput")WindowsError: [Error 32] The process cannot access the file because it is being used by another process

Membrane

Hi All,

I am running some flexible backbone design on a transmembrane four-helix bundle heme protein via RosettaScripts. I'm finding that the membrane residue is moving a lot during design, and I have to optimize the embedding with mp_transform post-design to reposition the mem residue. I have a few questions about this:

protein relax

I am trying to relax my protein with ligands FMN before do further design. I used movemap to exclude the rotamer on FMN. my flag and movemap file looks like below. I also attached my protein_FMN pdb. It takes an extremely long time and it seems like stuck somewhere (I attached the screen shot). Is it normal and anybody knows why? Thanks

flag file:

-in:file:s ./input/3TX9.A_FMN_Crystal.pdb

-in:file:movemap movemapfile

# Harmonic runs

-relax:constrain_relax_to_start_coords

Alanine Scanning for 1 Protein (no interface)

Hi, does anyone know how to do alanine scanning for just one protein?

I looked at different movers for RosettaScripts, like ddgScan, AlaScan, and ddg. Can any of these be used for a single protein with no interface? I want to see which protein residues are good targets for mutation.

"Angle constraint: 0-length bonds" error

Submitted by purvi24 on Sun, 2019-07-28 10:09

Hi,

I am trying to design the binding site of a protein with certain ligands and there is a common error that I encounter with various ligands (not all). The error says "Angle constraint: 0-length bonds". I checked the input structure and there are no atom clashes. I am not sure what is causing this error. If anyone has an idea, it would be a great help.

Thank you !

RosettaMatch

Hi,

I was trying to run rosetta match with Rosetta/main/source/bin/match.linuxgccrelease   

The match was done successfully with older version of rosetta, but didn't work with Rosetta 3.10. It aborted because of an error of "ERROR: Assertion 'build_sets_[ build_set_id ].restype().has( "1HA" ) failed. ERROR:: Exit from: src/protocols/match/upstream/ProteinUpstreamBuilder.cc line 1210". I was wondering if there's a way to fix this. Many thanks.

Enzyme Design FlexBB Protocol Bug: DNA/RNA handling

Submitted by kettner on Fri, 2019-06-14 14:16

Enzyme Design

Hi Folks,

I've been playing with the enzyme design binary application using enzymes containing DNA or RNA in the pose. The FlexBB protocol can be activated by setting the flag '-enzdes:flexbb_protocol true'. If no loop file is provided via the flag '-enz_loops_file <file>' the default  protocol behavior is to iterate through the pose to identify flexible regions in the structure for loop design. I found that having either DNA /RNA  in the pose triggers the following error consistently after cst minimization.

The question about FavorNativeResidue

Submitted by asbelx on Fri, 2019-04-12 20:02

Enzyme Design

 I  read the paper Rosetta and the Design of Ligand Binding Sites doi:10.1007/978-1-4939-3569-7_4.

 

then try to use  EnzRepackMinimize  to design the protein.

But FavorNativeResidue was set as 0.5-3.0, the mutant position numbers are same and there are too many mutant positions.

However, I use the PackRotamersMover  by changing  FavorNativeResidue and can get different mutant position numbers.

How can I solve it? Thanks.

Adding bridged water interaction in constraint file

Hi,

 

I am working on Rosetta Enzyme Design Application trying to design a protein with a particular ligand in desired geometry. I wanted to define a bridged hydrogen bond interaction between the carboxylate group on the ligand and the arginine residue in protein via water molecule.
