A Structural View of Biology

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.

Deposition Preparation Tools

Data Extraction

  • pdb_extract : Extract and harvest data in PDBx/mmCIF format from structure determination programs

Comparison Tool

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.

Peptidyl-carrier Proteins

Bacteria are creative chemists, constantly discovering new ways to build unusualmolecules for exploiting natural resources and fighting competitors. Many of these molecules look like short proteins, but they are not built the same way as traditional proteins. Instead of using the information in DNA, they are built using a dedicated assembly line of enzymes, each... Read More

Molecule of the Month



"To be, or not to be"--that question is continually being asked by each of your cells. Your cells are preprogrammed to die on command. This is essential during development of large organisms like ourselves, where cells work together, growing and dying to shape our complicated bodies. It is also essential throughout our adult lives, to remove damaged or infected... Read More
