Annotations from UniProt

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

UniProt annotations can also be fetched along with a sequence or mapped to a sequence already in Multalign Viewer regardless of whether the sequence is associated with a structure.

Sliced Potassium Channel

Potassium channel (Protein Data Bank entry 1bl8) on a dark slate blue background with potassium ions shown in firebrick. The channel is comprised of four chains. Each chain has been rainbow-colored from blue at the N-terminus to red at the C-terminus, but only the surface of the channel is shown. The surface has been sliced with a per-model clipping plane. The surface cap color is plum except with opacity set to 0.8. The shininess and brightness have been set to 128 and 8, respectively, and the lights on the scene have been moved from their default positions. The subdivision quality (related to the smoothness of the spherical ions) is 5.0, and the molecular surface was computed with probe radius and vertex density set to 1.0 and 6.0, respectively.
