First, don't get fooled by the mover _movers.KinaseMover that like the rest of the virtual enzymes is meant to work as a virtual enzyme with a target sequence and an efficiency. In pyrosetta things work a bit differently. GTP -GTP (be careful as a handful of structures have GDP with odd atom names).The pymol step could be easily automated in python, but then if one were to do that, using pyrosetta would make more sense. *) Note that this only works with 3.8 and above thanks to the addition of the PDB Chemical Components dictionary (CCD) business -this is normally a pain as it prevents parsing of custom params files with shared names with PDB ligands and has to be disabled with -load_PDB_components false. The file your_modded_model_0001.pdb will have the correct NCAA. $ROSETTA/score.$ROSETTAEXT -database $ROSETTADB -s your_modded_model.pdb -out:output -no_optH false VanderWaals’ torsional clashes (intraresidue)īackbone-backbone VanderWaals.In the terminal simply run the Rosetta score app* with pdb output enabled. This the contribution of sidechain-sidechain and sidechain-backbone HbondsĮnergy penalization due to VanderWaals’ clashes (interresidue) This is the predicted overall stability of your protein The files Dif_, Average_ and Raw_ have same headers with the energy terms decomposition in Kcal/mol, the colums are: Energy terms Output files contains the Gibbs energy of protein folding decomposed into the different terms used by FOLDX. PdbList_PDB_BM.fxout -> names of all the mutants and the corresponding WT references.Raw_PDB_BM.fxout -> full energy decomposition for the WT references and the mutants.Dif_PDB_BM.fxout -> energy difference between reference WT and the corresponding mutant.

Average_PDB_BM.fxout -> average energy of the different runs.

The option out-pdb is setted to true by default and can be use with commands as Pssm or PssmStability.įoldX uses output-file as a tag to label different outputs from different commands in batch runs. After running BuildModel you'll get three files to look at. However, sometimes it can be set to higher numbers (typically 5) to see if the algorithm has achieved convergence, or in other words if the solution offered is the optimal or a trapped solution. The parameter numberOfRuns tells the algorithm how many times it should do the specified mutations. The minimal configuration file for BuildModel:įoldX -command=BuildModel -pdb=BM.pdb -mutant-file=individual_list.txt

Build model requires a mutant-file to run. This command ensures that whenever you are mutating a protein you always move the same neighbours in the WT and in the mutant producing for each mutant PDB a corresponding PDB for its WT (each mutation will move different neighbours and therefore you need different WT references). This is the workhorse of FoldX mutation engine.
