Furthermore, in all the cases I mentioned in the previous posting, two of 
the histidine residues are on a helix, separated by three other residues 
(i.e. they are residues n and n+4, i.e. on the same face of the helix, 
which repeats with period 4 of course.)

Fee free to e-mail me if you want me to look at the structures in more 
detail.
