Match Application Error: Assertion `build_sets_[ build_set_id ].restype().has( "1HA" )` failed

大家好!

我想为新底物设计甲基转移酶。该酶依赖于小分子作为甲基供体 (SAH)。因此,我使用 -extra_res_fa 参数将 SAH 包含为应用的输入。CST 文件包含三个约束:约束 1 涉及底物和 HIS 残基,约束 2 涉及底物和 ARG 残基,约束 3 涉及底物和 SAH。而SAH位于PDB的最后一个块。

Error when running the CstfileToTheozymePDB Application

Hello,

I am relatively new to Rosetta, and i am trying to generate a constraint file (.cst) with my catalytic amino acid and ligand defined, that i am going to use to search against a PDB database. However, no matter how hard i try i keep obtaining this error:

Are catalytic residues mutatable?

Hi all,

I was running the integration test of the enzyme design (main/tests/integration/tests/enzdes). According to the fifth constraint block in the cstfile at position Trp100 residues WFY with atom type aroC are allowed. However within 150 output structures I never observe a mutation away from the native Trp. In contrast, residue Ser98 is variable in the results (only has backbone constraints). Similarly, I never observe any mutation away from a native catalytic sidechain in my own project.

Rosetta Design: Non-canonical amino acid substrate not accepted

I experience difficulties when submitting an enzyme PDB file with the
substrates AMP and a non-proteinogenic amino acid to the RosettaDesign webserver.
AMP is well accepted but problems arise with the amino acid substrate.

Converting all residues to poly-Gly/Ala

Hey, I am pulling my hair out over this. I am trying to convert all residues in a protein to poly-Gly/Ala (for example 1ae1.pdb) but cannot find the Rosetta function to do so. I am replicating a paper where they included code and output, the output appears to be typical Rosetta output (the .pdbs are like 3tzc___1.pdb) which I am assuming were generated with a Rosetta function.

Which application/mover should I use to evaluate the ddg between apo enzyme and enzyme binding with transition state?

Category:

Hi everyone:

        I used Enzyme Design application to get a series of enzymes with ligand(transition state of my target reaction). Now I want to inspect the free energetic change upon the protein transition state binding. 

        So I first look into the ddg_monomer application, and I find this application is suitable for comparing ddg energy between wild-type protein and its mutant structures. This can't meet my needs.
