protein databases

Protein databases are organized collections of information about proteins, which are essential molecules in all living organisms. These databases store data on protein sequences, structures, functions, and interactions. Scientists use them to understand how proteins work, how they interact within cells, and how they can be targeted in diseases. By accessing these databases, researchers can compare proteins from different species, discover new functions, and advance drug development. Examples of popular protein databases include UniProt and Protein Data Bank (PDB), which serve as valuable resources for biologists and medical researchers worldwide.
