Sequence Details pages for all protein structures now include a Jmol view of the structure that can display domain
annotations from SCOP, CATH, DP, PDP, Pfam, and InterPro.
During the past year, the wwPDB annotators have collaborated on a
project to clarify the details and procedures related to data
processing and annotation.
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.
A list of browsers known to work with this site and a browser compatibility check are available.
A narrated tutorial illustrates how to search,
navigate, browse, generate reports and visualize structures using this
site.

We are remarkably resistant to changes in our surrounding environment. Our bulky bodies allow us
to weather extremes of heat and cold, and our skin protects us if we go for a swim in fresh water
or salty water. If things get too uncomfortable, we can always get up and walk away, finding a
warmer or cooler or drier place. Bacteria don't have as many options. They are tiny and they are
immersed in water, so changes in the environment can pose life-threatening challenges. For
instance, if it rains they may be suddenly surrounded by fresh water. This is dangerous because
the water seeps into the cell through osmosis and increases the pressure inside. At other times,
the bacterium may be shifted suddenly to salty conditions, which pulls water out and dehydrates
the cell. Bacteria have methods for resisting these changes, so they can keep a steady, comfortable
osmotic pressure inside.
