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.
Use the Java Applet enabled form below to download the coordinates or experimental data for one or more structures.
If you are using Mac OSX, this feature doesn't work on Chrome's 32bit browser. Please use a 64 bit browser like Firefox.
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.

Calcium is used to control many cellular processes that require synchronized action. For instance, in muscle cells, large quantities of calcium are stored in special compartments, termed the sarcoplasmic reticulum, which is released in a flood to trigger contraction simultaneously throughout the cell. The ryanodine receptor is at the center of this process. It... Read More
Scientists have known for many years that plants respond to light, growing toward sources of light and protecting themselves from light that is too harsh. In many of these cases, plants are responding to the level of blue light. Blue light has several advantages over other colors. It is among the most energetic of the visible colors, and thus can have a greater... Read More
