The PDB/UniProt Info tool retrieves sequence and structure annotations for Protein Data Bank (PDB) entries using a Web service provided by the RCSB PDB. Sequences are displayed in Multalign Viewer, and feature annotations from UniProt are mapped onto the sequences as regions or colored boxes. In the region browser (figure at right):

• making a region Active selects any corresponding structure residues for further operations; only one region can be active at a time
• making a region Shown displays it in the sequence window
• the square color wells show (and allow changing) the region interior and border colors

BILD format was used in Chimera to annotate the barrel structure of green fluorescent protein with its centroid, major axis (red arrow), and an enclosing cylinder (shown with green hoops). The BILD file green.bild was generated with the python program green.py using the coordinates in green.pdb. Gallery entry courtesy of Mike Ess, Yeast Resource Center, University of Washington.
