Welcome to the RCSB PDB
The
RCSB
PDB provides a variety of tools and resources for studying the
structures of biological macromolecules and their relationships to
sequence, function, and disease.
The RCSB is a member of the
wwPDB whose mission
is to ensure that the PDB archive remains an international resource
with uniform data.
This site offers tools for browsing, searching, and reporting that
utilize the data resulting from ongoing efforts to create a more
consistent and comprehensive archive.
Information about compatible browsers can be found
here.
A
narrated tutorial illustrates how to search,
navigate, browse, generate reports and visualize structures using this
new site.

Ribonuclease A is the enzyme that digests RNA in our food. Because is
it small, stable, and easily purified, ribonuclease has been an
important enzyme in biochemical research. It was used by Christian
Anfinsen to prove that the sequence of amino acids determines the
structure of a folded protein and it was used by Stanford Moore and
William Stein to show that a specific arrangement of amino acids is
used in the catalytic center of enzymes. Ribonuclease A was also the
first enzyme synthesized by R. Bruce Merrifield, showing that
biological molecules are simply chemical entities that may be
constructed artificially. All of these central concepts, discovered
with the help of ribonuclease, were awarded Nobel Prizes.
