Hello world, 

I am writing a program for the determination of the 3D-structure of
proteins using genetic algorithms. My problem is that when I generate
Ramachandran plots to contraint the torsion angles, the Ramachandran plots
for l-alanyl like residues and d-alanyl like residues look rather different,
the l-alanyl like residues are similar to literature, but I don't have 
literature for d-alanyl like residues, can anybody give a reference to 
that, or tell me what the difference between these two Ramachandran plots
must be? 
ps. The glycyl-like residues and l-alanyl residues succeeding a proline also
look like literature (Book : biophysical Chemistry by Cantor & Schimmel)
