gP2S, an Information Management System for CryoEM Experiments

Area of Science:

• Structural Biology
• Biophysics
• Drug Discovery

Background:

• Cryogenic electron microscopy (cryoEM) is crucial for structure-based drug design when crystallography is not feasible.
• Managing numerous projects and ligand-protein co-structures in cryoEM presents significant record-keeping challenges.
• Accurate experimental parameter tracking is vital for reproducibility and efficient teamwork in cryoEM.

Purpose of the Study:

• To develop a web-based information management system for organizing cryoEM experimental workflows.
• To address the challenges of accurate record-keeping in large-scale cryoEM drug discovery projects.
• To enhance reproducibility and facilitate collaboration among researchers in cryoEM studies.

Main Methods:

• Developed gP2S, a web-based information management system for cryoEM.
• Implemented user-defined controlled vocabularies for consumables, equipment, protocols, and software.
• Integrated with external systems via REST APIs for broader application ecosystems.
• Recorded experimental details including metadata and parameter values for samples, grids, and microscopy sessions.

Main Results:

• gP2S tracks experiments from sample to atomic model within project contexts.
• The system records the lineage of experimental artifacts, ensuring data traceability.
• gP2S supports structured description of cryoEM workflow steps using configurable vocabularies.
• The system is widely configurable and integrates with other scientific applications.

Conclusions:

• gP2S effectively organizes cryoEM experimental workflows, enabling accurate record-keeping for research teams.
• The system enhances reproducibility and facilitates efficient collaboration in drug discovery projects.
• gP2S is available as an open-source solution, promoting wider adoption in the scientific community.
