## mutation.py test
|
||
|
||
### evoEF2 test
|
||
|
||
#### install
|
||
|
||
```shell
|
||
unzip EvoEF2-master.zip
|
||
cd EvoEF2-master
|
||
./build.sh
|
||
```
|
||
|
||
```shell
|
||
python mutation.py evoef2 -p 4i24.pdb -m test.list
|
||
```
|
||
|
||
### foldX test
|
||
|
||
```shell
|
||
python mutation.py foldx -p 4i24.pdb -m test.list
|
||
```
|
||
|
||
### rosetta test
|
||
|
||
```shell
|
||
python mutation.py rosetta -p 4i24.pdb -m test.list
|
||
```
|
||
|
||
### scwrl4 test
|
||
|
||
install : `chmod +x install_scwrl4.0.2_64bit_2020_linux`
|
||
|
||
```shell
|
||
python mutation.py scwrl4 -p 4i24.pdb -m test.list
|
||
```
|
||
|
||
### opus-mut test
|
||
|
||
1. Use mk_mut_backbone.py to generate original WT backbone file and mutants backbones.
|
||
In this step, you need to set the original PDB file path in line 97 native_filepath = ./3phv.pdb. Then set the mutations you want in line 108 mutations = ["P9Y", "V82I", "V82G", "I84N", "L90R"]. Here, we use hiv.pdb and mutation Q2E as an example.
|
||
|
||
2. List the backbone paths in bb_list.
|
||
ls *bb > bb_list
|
||
|
||
3. Use run_opus_mut.py to generate the results of OPUS-Mut (.mut).
|
||
In this step, you need to activate the environment created by mut.yml file. Also, a GPU device is required and should be set in line 13 os.environ["CUDA_VISIBLE_DEVICES"] = "0". cuda10.1 is also required.
|
||
|
||
4. Use get_difference_summation.py to calculate the differences between WT and mutants (.changes).
|
||
In this step, you need to set the original PDB file name in line 20 ori_name = "3phv", and line 115 if filename == "3phv": continue. Note that, the code line 130 if not int(resid) in [25, 26, 27]: continue can be used to calculate the differences from specific residues (Sdiff_critical). When calculating the differences from all residues (Sdiff), you need to comment this line, and also uncomment the line between 134-143 to avoid the influence of outliers. .
|
||
|
||
根据opus-mut的软件使用教程来看，opus仅支持单链进行突变，也就是说如果需要对多链进行突变，需要对多链单链分割，然后对分割后的多链进行突变，然后再将突变后的单链进行合并。
|
||
|
||
注意opus-mut需要从[github仓库](https://github.com/thuxugang/opus_mut/tree/main)获取
|
||
|
||
### pymol test
|
||
|
||
```shell
|
||
python mutation.py pymol -p 4i24.pdb -c B -r 797 -t GLY
|
||
```
|
||
|
||
### 统一接口调用
|
||
|
||
完成 2023-08-22
|
||
|
||
### 调用方法统一为 test.list文件（方便多位点突变）
|
||
|
||
完成 2023-08-25
|
||
|
||
### 封装环境至docker镜像
|
||
|
||
### 使用scwrl4进行残基序列突变
|
||
|
||
测试：
|
||
|
||
```shell
|
||
python mutation.py scwrl4 -p 4i24.pdb -m test.list
|
||
```
|
||
|
||
## construct docker images
|
||
|
||
```shell
|
||
docker cp /home/share_data/opus_mut.zip a97ed867a713:/work
|
||
```
|
||
|
||
## Docker 镜像使用
|
||
|
||
```shell
|
||
rm ../dockertest/* -rf && cp ../4i24.pdb ../dockertest && cp ../test.list ../dockertest
|
||
docker run --rm -it -v /home/zenglingyu/tools/dockertest:/work hotwa/mutation:latest <software> -p /work/4i24.pdb -m /work/test.list
|
||
# example
|
||
docker run --rm -it -v /home/zenglingyu/tools/dockertest:/work hotwa/test2:latest rosetta -p /work/4i24.pdb -m /work/test.list
|
||
docker run --rm -it -v /home/zenglingyu/tools/dockertest:/work hotwa/test2:latest scwrl4 -p /work/4i24.pdb -m /work/test.list
|
||
docker run --rm -it -v /home/zenglingyu/tools/dockertest:/work hotwa/test2:latest evoef2 -p /work/4i24.pdb -m /work/test.list
|
||
```
|
||
|
||
### 非root测试
|
||
|
||
```shell
|
||
docker run --rm -it -v /home/zenglingyu/tools/dockertest:/home/developer/work hotwa/test1:latest rosetta -p /home/developer/work/4i24.pdb -m /home/developer/work/test.list
|
||
```
|
||
|
||
### 构建docker镜像
|
||
|
||
缺少`pyrosetta-2023.31+release.1799523-py311_0.tar.bz2`文件，需要从官网下载手动安装，太大了。上传太慢

### 突变文件介绍
|
||
|
||
突变文件格式
|
||
文件名: individual_list.txt
|
||
|
||
内容结构:
|
||
|
||
每个突变写在一行上，以“;”结束。
|
||
一个突变中的多个单点突变用“,”分隔。
|
||
突变表示:
|
||
|
||
第一个字母是参考氨基酸（原氨基酸）。
|
||
第二个字母是氨基酸所在的链标识符。
|
||
紧跟着的数字是氨基酸在链中的位置。
|
||
最后一个字母是突变后的氨基酸。
|
||
示例:
|
||
|
||
```shell
|
||
CA171A,DB180E;
|
||
```
|
||
|
||
|
||
第一个突变：链A上位置171的C（半胱氨酸）突变为A（丙氨酸）。
|
||
第二个突变：链B上位置180的D（天冬氨酸）突变为E（谷氨酸）。
|
||
注意:
|
||
|
||
不应有空格或其他多余字符。
|
||
这种格式允许用户明确指定在蛋白质复合体中哪些氨基酸应进行突变，从而提供高度定制的突变模型。
|

pymol仅突变，修复突变残基周围的构象
|
||
|
||
scwrl4: 只能预测侧链，会改变蛋白构象

||
|
||
