Could you have an unexpected "small subunit" (or some other situation)
giving additional density that Phenix is building into ? In other words,
how sure are you of what is present in the crystal ? This is because I
remember the enzyme methanol dehydrogenase where there was a small
subunit which had not been evidenced for years...
