Is it possible to model peripheral membrane proteins?
I know RosettaMP is useful to model transmembrane proteins, but I don't know whether it is applicable for peripheral membrane proteins or not.
Thanks.
Hello Rosetta community
I need to score a membrane protein using PyRosetta and am having trouble with the implementation. The 2014 post in the forum has not been very helpful in terms of syntax, and there is little to no documentation. I see a tutorial is in the works on the website, but if anyone has advice right now that would be greatly appreciated. A working (minimal) example would probably be most helpful, something I can work off of.
Thank you
Joel
If I run this command:
residue_energy_breakdown.static.linuxgccrelease -in:file:s hasDUMresidues.pdb -out:file:silent energy_breakdown.out -ignore_unrecognized_res true
on the attached pdb, I get this error:
caught exception
Hi,
I'm trying to generate the input files for membrane ab-initio. I already created the span file using OCTOPUS.
However, the run_lips.pl script keeps failing. It creates blast outputs (blast and blast.msa files) but the raw file is empty and the lips4 file contains only the header, and the lipo file is also without values.
I think there's some problem with the part running this script- "http://gila.bioengr.uic.edu/cgi-bin/lips/script.cgi".
Can anyone help me with that?
Is it possible to combine a flags file with command line arguments?
For example, something like this:
minimize_with_cst.linuxgccrelease -in:file:l min_pdb_file_list @flags_file
where flags_file contains additional options. Moreover, what is the effect of changing the order of command line arguments and flags files? Which takes precedence? That is, what is the difference between the above command and:
minimize_with_cst.linuxgccrelease @flags_file -in:file:l min_pdb_file_list
Thanks.
I have run Rosetta membrane successful in the past, but it seems that now the blastpgp database necessary to run the run_lips.pl script is obsolete.
In the lastest BLAST release, blastpgp has been dropped entirely in favor of psiblast.
I am then blocked and I cannot generate the lips4 file using:
run_lips.pl <fasta file> <span file> <path to blastpgp> <path to nr database> <path to alignblast.pl script>
Is there a way of the run_lips.pl connecting the psiblast, or does it need to be modified?
Dear all,
I am a new Rosetta (3.5) user and I would like to study the effects of some point mutations on a monomeric transmembrane protein.
Can ddg_monomer properly predict the change in stability induced by point mutations in transmembrane proteins? If yes, should I specify a particular score function file using -ddg:minimization_scorefunction option? I would like to study mutations in both, the transmembrane (membrane-facing and not) and the extracellular region of the protein, should I treat them separately?
