Researchers at IRB Barcelona's Molecular Modelling and Bioinformatics lab have released a revolutionary database for molecular dynamics simulations.

The work has been published in the journal Nucleic Acids Research.

Designed to meet the urgent need for insights into the molecular intricacies of SARS-CoV-2 infection, BioExcel-CV19 is a repository for Molecular Dynamics (MD) simulations. Researchers at IRB Barcelona, led by Dr. Modesto Orozco, have built this database including key flexibility information essential for understanding the roles of key proteins in the virus, such as the Spike protein, Receptor Binding Domain (RBD), and RNA-dependent RNA polymerase (RdRp), providing over 10,000 trajectories.

“This database represents a shift in molecular dynamics databases, built to handle large systems and long trajectories while seamlessly integrating with modern MD simulations”, explains Dr. Modesto Orozco, head of the Molecular Modelling and Bioinformatics lab at IRB Barcelona and University of Barcelona professor. “It brings together trajectories contributed by diverse research groups, showcasing a collaborative approach that drives scientific discoveries,” he adds.

The article, published in Nucleic Acids Research, not only highlights the features of BioExcel-CV19 but also underscores the importance of storing MD simulations. Stored simulations ensure result reproducibility and facilitate community-wide analysis. “Platforms like BioExcel-CV19 should become a standard, akin to the Protein Data Bank (PDB) in structural biology,” states Dr. Adam Hospital, a Research Associate at IRB Barcelona, who has led this work together with Dr. Orozco. 

BioExcel-CV19's impact extends to various scientific domains, including virology, genomics, structural and molecular biology, drug design, biomolecular simulation, and machine/deep learning. The open data provided becomes a valuable resource for training models, influencing fields that use data for various purposes.

In the field of biomolecular simulation, BioExcel-CV19 provides a wealth of data for refining algorithms and MD force fields. The potential for re-analysis and reuse of data opens avenues for new discoveries and meta-analyses, making BioExcel-CV19 a valuable asset for the scientific community.

Future efforts of the lab will focus on advancing BioExcel-CV19, ensuring it evolves with the ever-changing landscape of COVID-19 research. The database will see continuous updates with new simulations and user-suggested analyses, fostering ongoing collaborations and discoveries.

BioExcel-CV19 also serves as a prototype for an ambitious project called MDDB. Coordinated by IRB Barcelona, this European endeavour aims to design a European Repository for Biosimulation Data. With a consortium including the University of Oxford, Barcelona Supercomputing Center (BSC), CECAM, EMBL-EBI, KTH, and Nostrum Biodiscovery (NBD), MDDB represents a pioneering step towards federated and distributed infrastructures.

The development of BioExcel-CV19 has been made possible through the support of three EU-funded projects: BioExcel Centre of Excellence (BioExcel CoE), Human Brain Project (HBP), and Molecular Dynamics Data Bank (MDDB). Special thanks go to the Red Española de Supercomputación (RES-Data) for providing the necessary data storage resources.

BioExcel-CV19 is a web-based portal and provides an accessible gateway for users to explore and query data interactively. For more information, visit:
