Dear Chris and Leo, Thank you for your suggestions.
I am refining the 1.08 A structure in SHELXL and I have Hs added; I think refinement is at a final stage. I did start with the 50%, 25+25% occupancy but then I changed to 0.33 each ... I need to refine this further. For the 1.35A data, model is complete (except for some C- and N-terminal residues) and I've refined alternative conformations too. The crystallization condition is Sodium acetate and PEG3350 with ethylene glycol as cryo. I have some molecules of cryo and Na in the model. I’ll try other cat/anions and refine. Best, Fátima
