View 1ENY in 3D

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 1ENY

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. STING, shows the sequence and maps the locations of sequence residues or residue ranges onto the 3D structure.
