A Resource for Studying Biological Macromolecules
The PDB archive contains information about experimentally-determined structures of proteins, nucleic acids, and complex assemblies. As a member of the wwPDB, the RCSB PDB curates and annotates PDB data according to agreed upon standards.
The RCSB PDB also provides a variety of tools and resources. Users can perform simple and advanced searches based on annotations relating to sequence, structure and function. These molecules are visualized, downloaded, and analyzed by users who range from students to specialized scientists.
Our cells are filled with compartments, each performing a specific function. Some of these
compartments, such as mitochondria and lysozomes, are very large and enclose many
different molecular machines. Other intracellular compartments are smaller, such as the
transport vesicles that shuttle proteins from site to site inside the cell. Most of these
compartments, including mitochondria, lysozomes and transport vesicles, are surrounded by
membranes. However, in special cases, cells build smaller compartments surrounded by a
protein shell. In our own cells, vaults are a spectacular example of these protein-enclosed
compartments.

Drug-resistant strains are continually emerging as bacteria evolve and share new methods to
shield their antibiotic-sensitive machinery, or destroy antibiotics directly. Today, we are
searching for new approaches to fight our microscopic enemies using the tools of structural
and molecular biology. A recent structure of lysostaphin reveals the atomic details of a
magic bullet against Staphylococcus aureus infections.
