PlaPPISite is a new database detailing plant protein-protein interactions (PPIs) and their 3D structures. This resource aids plant systems biology research by providing crucial interaction site information for understanding cellular machinery.
Area of Science:
- Plant Biology
- Structural Biology
- Bioinformatics
Background:
- Systematic characterization of protein-protein interactions (PPIs) is essential for understanding cellular functions.
- Existing plant PPI data lacks detailed three-dimensional (3D) structural information of interaction sites/interfaces.
- The demand for accessible 3D structural data of plant PPIs is growing, especially in the post-AlphaFold2 era.
Purpose of the Study:
- To develop and introduce PlaPPISite, a user-friendly database for plant PPIs.
- To provide detailed interaction site information, including 3D structural contexts, for 13 plant interactomes.
- To guide users on accessing and utilizing PPI data within the PlaPPISite database.
Main Methods:
- Development of the PlaPPISite database.
- Inclusion of data for 13 plant interactomes.
- Provision of a user guide detailing database navigation, input formats, and information retrieval.
Main Results:
- PlaPPISite offers a comprehensive resource for plant PPIs with detailed interaction site information.
- The database facilitates the visualization and analysis of 3D structural contexts of protein interactions.
- Examples demonstrate how to retrieve specific interaction site data relevant to biological questions.
Conclusions:
- PlaPPISite enhances the study of plant systems biology by providing crucial 3D interaction data.
- The database is a valuable tool for deciphering molecular mechanisms underlying biological processes in plants.
- Accessible 3D structural information of PPIs will accelerate research in plant biology.
