Problem with relaxing a PDB around a chemically bound ligand

Category: 
Small Molecules


Hello,

I have downloaded a PDB with a chemically bound ligand (small molecule)

I have followed (in every way that I can see) all the details presented in the tutorial/demo here:

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。

I am still working on the Cao protocol. And I ran into another problem. When I ran step 15: Motif extraction. I ran the following command:

Dear ROSIE2 team,

thank you very much to making available such a great ressource.

I used the ROSIE2 server and AlphaRed to predict protein-protein interactions. While it works most of the time, I would like to share some of the error messages which I experience regularly. Maybe they help you to improve the software.

Are catalytic residues mutatable?

Category: 
Enzyme Design
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.

peptide design

Category: 
Design

Hi, 

I have a protien peptide complex and I want to design a peptide that will bind to the protein better the the WT peptide. What tools do you suggest I use? it can also be from

any of the other rosseta platform (or any other). My goal is to find 50 potential peptides and then test them experimentally.

Thanks, 

Miriam
