Lligand

Un lligand és una substància que forma un complex amb una biomolècula per servir un propòsit biològic. L’etimologia prové del llatí ligare, que significa ‘unir’.

En la unió proteïna-lligand, el lligand és generalment una molècula que produeix un senyal en unir-se a un lloc específic d’una proteïna objectiu. La unió típicament resulta en un canvi d’isomerisme conformacional (conformació) de la proteïna objectiu.

Python

Python offers a range of libraries and tools that facilitate molecular docking simulations and analysis. Some popular Python libraries used in molecular docking are:

• PyAutodock: PyAutodock is a Python wrapper for the popular docking software AutoDock Vina. It allows you to perform molecular docking studies using AutoDock Vina from within Python and enables programmatic control of the docking process.

• PyRx (Python Prescription): PyRx is a virtual screening tool that utilizes Autodock Vina under the hood. It provides a user-friendly graphical interface but also offers a Python API for more advanced users who want to automate tasks or perform custom analyses.

• Open Babel: Open Babel is a chemical toolbox designed to speak the many languages of chemical data. It can be used to convert molecular file formats and manipulate molecular structures, which is often useful in preparing input files for docking simulations.

• RDKit: RDKit is another versatile cheminformatics library that can handle molecular data, including 2D and 3D molecule rendering, chemical transformations, and property calculations, which can be beneficial in preparing ligands and protein structures for docking studies.

These libraries provide functionalities to set up docking simulations, analyze docking results, visualize interactions, and perform further analysis. Additionally, with Python’s extensive scientific ecosystem, you can combine these libraries with others for data manipulation, visualization, and statistical analysis, making it a popular choice for researchers and scientists in the field of molecular docking.
