Dear all,
in my maps (green is fo-fc at 4sigma) I have density that I cannot (I
think) attribute to anything from the crystallization conditions (MPD,
Na-acetate, CaCl2) or the protein storage buffer (Hepes, NaCl, NaN3). 2
images (90 degres) can be seen at :
http://unknowndensity.blog4ever.com/blog/photo-183078.html
The middle of this density (pink cube) is on a special position and is
surrounded by charged residues from 2 symetrical molecules.
Any ideas will be welcome.
Thanks in advance,
Franck.
