Use these educational features to explore the world of proteins and nucleic acids
This resource is powered by the Protein Data Bank archive-information about the 3D shapes of proteins, nucleic acids, and complex assemblies that helps students and researchers understand all aspects of biomedicine and agriculture, from protein synthesis to health and disease.
As a member of the wwPDB, the RCSB PDB curates and annotates PDB data.
The RCSB PDB builds upon the data by creating tools and resources for research and education in molecular biology, structural biology, computational biology, and beyond.
Use this website to access curated and integrated biological macromolecular information in the context of function, biological processes, evolution, pathways, and disease states.
The Jmol molecular viewer offers several options for display and analysis.
Launch the viewer using the 3D View feature from any entry's Structure Summary or by entering an ID below. Learn more about Jmol.
PDB ID: 4HHB
PDB ID: 1STP
PDB ID: 4EAR
RCSB PDB's Comparison Tool calculates pairwise sequence (blast2seq, Needleman-Wunsch, and Smith-Waterman) and structure alignments (FATCAT, CE, Mammoth, TM-Align, TopMatch).
Comparisons can be made for any protein in the PDB archive and for customized or local files not in the PDB.
Special features include support for both rigid-body and flexible alignments and detection of circular permutations.

Articles describe the structure and function of a molecule, offer interactive views and discussion topics, and links to specialized pages to help explore specific example structures.
The PDB archive is updated weekly in two phases
Phase I: Every Saturday by 3:00 UTC, for every new entry, wwPDB website provides sequence(s) (amino acid or nucleotide) for each distinct polymer and, where appropriate, the InChI string(s) for each distinct ligand.
Phase II: Every Wednesday by 00:00 UTC, all new and modified data entries will be updated at each of the wwPDB FTP sites.

Green fluorescent protein (GFP) has proven to be an invaluable scientific tool, allowing researchers to pinpoint the location of GFP-tagged proteins inside living cells. The discovery of GFP-like proteins with different colors in Nature has made this even more useful, allowing researchers to study multiple proteins simultaneously. Currently, researchers are...

Titin is the largest protein chain in your body, with more than 34,000 amino acids. This titanic protein acts like a big rubber band in our muscles. It is attached at one end to the Z-disk (shown here at the top in blue), which organizes the thin actin filaments. The other end of titin is attached to the M-line (shown in red at the bottom), which organizes the... Read More
