Hi Bing,

This is the result of the new PDB deposition system being buggy. I had a 
similar problem with imidazole recently. This is the solution given to me by 
the PDB annotators.

Hope this helps,
Katherine

What makes you think so?

unlikely.

It is not clear to me what test you are performing.  I do note that the
SMILES for HEM in the CCD doesn't contain Fe - that might be related.

HTH,
