I'm in the later stages of solving a structure which contains two
tetramers in the asymetric unit. I found these two blobs (in
equivalent positions on each tetramer) with positively charged
residues around it. Crystallization condition is Magnesium chloride,
Bis-tris and PEG3350. While the second blob looks like a metal, the
first one has a weird shape even though they are expected to have the
same thing. Any ideas?
