Dear all
in my structure I think I can see an oxidised Cys in cys-SO. Refining cys-SO
I observe a residual density between the oxigen of one oxidised cys and the
one of the other molecule in AU.
I'd like to try to refine it as cys-SO-OS-cys. I didn't find an example of
it in the pdb database. Could anyone tell me whether there are other cases?
I guess I just didn't find them.
Second question:
How could I "explain" to refmac that there is the OO bond?
I tried to write a line similar to the one for SSBOND in the pdb header
OOBOND 1 CEA A 42 CEA D 42
but refmac couldn't care less...

thanks in advance

Stefano
