Introduction:
Think of pathway databases, like KEGG (Kyoto Encyclopedia of Genes and Genomes), as detailed maps that show you the intricate pathways inside living organisms. They're like digital guides that help scientists understand how different molecules, like proteins and metabolites, interact with each other to carry out various biological processes.
Imagine you're exploring a new city, and you have a map that shows all the streets, landmarks, and how they're connected. KEGG is similar, but instead of streets, it shows pathways—complex networks of molecules working together in cells.
In KEGG, scientists can find information about different pathways involved in processes like metabolism, signal transduction, and diseases. It's like having a roadmap to navigate through the molecular world of cells.
For example, if a scientist is studying a specific disease, they can use KEGG to explore the pathways associated with that disease. They can see which genes and proteins are involved, how they interact, and how they might be targeted for treatment.
Overall, pathway databases like KEGG are invaluable resources for researchers. They help them unravel the complexities of biological systems and uncover new insights into health, disease, and how living organisms function at the molecular level.
