How to determine the VH-VL orientation angle in rosetta. i came across this manuscript "Improved prediction of antibody VL–VH orientation" by Protein Eng Des Sel. 2016 Oct; 29(10): 409–418. Here there is description of MT protocol. Whether the script is provided in the rosetta 3.1 version. Or is there any other alternative in rosetta to calculate the VH-VL orientation (LHOC) angle of antibody in rosetta.
We're trying to model a membrane peptide of ~50 aminoacids which likely assumes beta-strand conformation in the membrane. Can we do this with the current Ab Initio membrane implementation of Rosetta? I know that we should use Octopus to generate a span file, but I'm left with the impression that it's designed for alpha helical proteins and that Rosetta in general is biased toward generation of alpha helices. Is there a way to enforce some beta-sheet restrictions during the ab initio folding process?
I'm getting a problem running the LHOC angle script in the antibody modeling protocol. To reproduce:
python -m pdb ../rosetta/main/source/scripts/python/public/plot_VL_VH_orientational_coordinates/plot_LHOC.py -h3_fasc H3_modeling_scores.fasc -graft_dir grafting -output_dir vhvl
I have uploaded the H3_modeling_scores.fasc file and the contents of the grafting directory. Here is the error message:
I want to use RosettaCM for density guided homology modeling. My structure contains taxol and other ligands: GTP and GDP, but my /rosetta/main/database/scoring/score_functions/facts contains params files for just GTP and GDP but not taxol. I atatched my taxol.pdb file for reference.
Thanks in advance.
I am docking an antibody that has 20 residues in the H3 loop. I realize that this is a very challenging case. From the 2017 paper by Weitzner and Gray, I understand the importance of a kink constraint in H3 loop modeling. I want to know if the H3 loop remodeling that occurs during snugdock includes the kink constraint. If not, I am concerned that the kink will be lost during remodeling, especially for this long loop.
Hello Rosetta devs,
I'm not sure that this is the right place to post a bug. If not, please let me know where to post.
I compiled both Rosetta 3.10 (and then 2019.07 release), and faced the following error when trying to predict cyclic peptides with terminal disulfide bonds using the simple_cycpep_predict protocol.
To be more specific, my peptide has a non-terminal CYS residue at the C-term, and I was using the
I am reading about the Abinitio protocol to see how I can include a checkpoint file in the Abinitio flags, but i could not find any information on how to input a checkpoint file. so this is my question:
- can I input a checkpoint file into Abinitio? if i can what is the flag -in:file: ?
