View 1XKW in 3D

Proteopedia, because life has more than 2D. On Jmol, a nice Rasmol like molecule viewer. This is good for easiest viewing of basic structure. On FirstGlance, an excellent tool for a guided tour on the structure components, by E. Martz. On AstexViewer, from MSD-EBI (viewer documentation). On RasMol (Install RasMol freeware) Here's help on how to use RasMol.

Visual 3D analysis of 1XKW

Protein Explorer, Easier to use and more powerful than RasMol. (Win and Mac only) Noncovalent Bond Finder displays the closest contacts to ligand or interface, reports distances, walks over water bridges. Cartoon representation from PDB Cartoon Ramachandran plot from PDBSum
