PDB Side Chain - Sec. Structure Analyses

[Wendy Cornell]

I have been using a 1987 JMB paper by McGregor, Islam, and
Sternberg which summarizes the correlation between preferred
side chain dihedrals and secondary structure type for each
of the amino acids.  Does anyone know of a similar analysis
carried out on a more recent version of the PDB?

Thanks,
