FragMAXapp: crystallographic fragment-screening data-analysis and project-management system

Acta Crystallogr D Struct Biol. 2021 Jun 1;77(Pt 6):799-808. doi: 10.1107/S2059798321003818. Epub 2021 May 14.


Crystallographic fragment screening (CFS) has become one of the major techniques for screening compounds in the early stages of drug-discovery projects. Following the advances in automation and throughput at modern macromolecular crystallography beamlines, the bottleneck for CFS has shifted from collecting data to organizing and handling the analysis of such projects. The complexity that emerges from the use of multiple methods for processing and refinement and to search for ligands requires an equally sophisticated solution to summarize the output, allowing researchers to focus on the scientific questions instead of on software technicalities. FragMAXapp is the fragment-screening project-management tool designed to handle CFS projects at MAX IV Laboratory. It benefits from the powerful computing infrastructure of large-scale facilities and, as a web application, it is accessible from everywhere.

Keywords: drug discovery; fragment screening; fragment-based lead discovery; high-throughput data analysis; protein crystallography.
