[phenixbb] polygon and membrane proteins

[Patrick Loll]

I don't know how easy this would be to do, but...

Steve White maintains a nice up-to-date database of membrane proteins  
of known structure (http://blanco.biomol.uci.edu/Membrane_Proteins_xtal.html 
). Since he has tabulated all of the PDB IDs, it should be trivial for  
him to supply just a list of the four-letter codes, which could be  
used as a filter.
