ARCTIC-3D: all you want to know about protein-specific interfaces

ARCTIC-3D is a software for data-mining and clustering of protein interface information. It allows you to retrieve all the existing interface information for your desired protein from the PDBE graph database (https://www.ebi.ac.uk/pdbe/pdbe-kb/), grouping similar interfaces in interacting surfaces.

The software first checks your input (a uniprot ID, a FASTA file, or a PDB file), and then retrieves the existing interaction data from the graph API. Such interfaces are projected on a selected PDB structure and their dissimilarity is calculated, thus allowing for the application of a hierarchical clustering algorithm.

In output you will see how your favourite protein can display different binding surfaces, each one characterised by few residues that are always present (hotspots) and other amino acids which are at the interface only from time to time.

Installation

With conda

Clone the repository on your computer and navigate to it

git clone git@github.com:haddocking/arctic3d.git
cd arctic3d

Here you can create the arctic3d environment:

conda create -n arctic3d python=3.10
conda activate arctic3d
pip install .
arctic3d -h

To run BLAST locally

bash install_blast_deps.sh

And put blastp in your $PATH by adding the following line to your .bashrc or .bash_profile file:

export PATH="PATH_TO_YOUR_ARCTIC3D_INSTALLATION/src/ncbi-blast-2.15.0+/bin:$PATH"

Example usage

Please refer to the examples documentation page.

Detailed documentation

In order to generate a detailed html documentation please execute these commands

pip install myst_parser
pip install chardet
conda install sphinx
sphinx-build -E docs ./arctic3d-docs

Then you can open the file arctic3d-docs/index.html, which contains all the necessary documentation.
