View 1T29 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.
