As Udock2 is designed to be used on low-end computers, we improve its construction using a time-tested grid-based generation method which has been leveraged several times ( Hermosilla et al. The global shape of the proteins involved in the interaction is represented using their Solvent-Excluded Surface (SES) ( Richards 1977). We then selected the protein’s shape and its electrostatics as the representation provided in UDock2. The goal of protein docking is to identify the best geometry of the complex by optimizing the binding energy between the two or more partners involved in the interaction. In the following parts, we describe UDock2’s main features and their contribution to the general goals of the software. To support the use of UDock2, we provide a tutorial video as supplementary material. The Bullet Physics SDK ( ) (Coumans) was used to handle the manipulation of molecular objects and the collision meshes. This development has been achieved with plain C++ and OpenGL.

Exploratory geometries can afterward be optimized using molecular simulation software to produce accurate solutions. Finally, UDock2’s exported files can be used in a molecular simulation or molecular visualization software in order to pursue the analysis. Proposed geometries can be exported in any molecular file format supported by the Chemfiles library ( Fraux et al.

This helps the understanding of the complex phenomena involved in molecular binding. The manipulation of molecules in the 3D environment is oriented toward binding score awareness to guide the exploration. UDock2 takes as input all-atom mol2 format files that include atomic partial charges to provide a way to explore, visualize, understand, and manipulate molecular entities. UDock2 has been designed to take advantage of the possible solutions proposed interactively by the users, as a part of a protein–protein interactions exploration pipeline.

Protein–protein docking simulation is usually computationally intensive and performed by automated software lacking intuitive user interaction features. Since UDock2 is also designed for educational and popularization of science purposes, we improved the gamification of the molecular docking sequence by providing a more playful experience. We introduce an extended navigation allowing to ease the exploration of molecular complexes by orienting the camera relatively to the molecular surface and user inputs. We provide the ability to study complex molecular systems, especially through the support of multi-body molecular docking thanks to an adapted energy computation scheme. To offer up-to-date features, a complete rewrite has been achieved which comes with several user experience improvements thanks to recent computer graphics strategies. The main UDock features were retained to be integrated into a research workflow with the following extended features: It therefore relies on standard CPU computing strategies and do not use any feature set restricted to modern GPUs. In order to broaden its potential audience, UDock2 is designed to be used on low-end computers. 2014), an intuitive and interactive multi-body protein–protein docking method oriented toward its ease of usability. In this article, we describe UDock2, the new version of UDock ( Levieux et al. 2020) for the popularization of such methods, combining performance, user-oriented features, and comprehensive feedback for interactive manipulation is still a complicated task.

Even though several works presented alternative approaches ( Lu et al. Different interactive docking methods have been released over time that notably suffers from limited usability and/or dependency on proprietary or expensive hardware ( Daunay et al. The manipulation and visualization of molecular bodies through an ergonomic and intuitive user interface in docking software still represent a challenge. By providing insight into the spatial arrangement of proteins and their binding sites, protein–protein docking simulations offer a valuable tool for understanding the mechanisms underlying complex biological processes. Such simulations have been shown to be effective in ranking the predicted geometries based on their binding energy, calculated using a molecular mechanics force-field ( Meng et al. To explore the geometry of these interactions, researchers have utilized protein–protein docking simulations, which aim to predict the relative position of the involved proteins. The critical involvement of protein–protein interactions in essential biological processes, including immunity and inflammation, has been well-established ( Braun and Gingras 2012).
