Defining specific restraints on bonds connecting the chromophore with the
rest of the protein worked fine for us in Refmac when we solved a turboGFP
structure a couple of years ago. There wasn¡¯t anything special that had to
be done ¨C all strictly by the book¡­

Subject: [ccp4bb] chromophore in GFP



Hi everybody,



we have solved the X-ray structure of a GFP (green fluorescent protein)
containing complex. During refinement of the structure we now encountered
the problem of connecting the GFP chromophore covalently to the polypeptide
chain. We introduced the chromophore to our model as a separate ligand with
separate toplogy. So far we could not find a way to integrate it in the
primary sequence.



Any idea how this problem can be solved? Which programs might be useful?



Thank you very much in advance.



Best,



Sheng & Axel
