I am a Ph.D. student at Prof. dr. H. Schenk's Laboratory for Crystallography
in Amsterdam. For my research in the field of Direct Methods in protein
crystallography I am looking for some suitable X-ray data-sets from solved
proteins. For my research suitable data-sets should comply with the following
* The protein contains between 25 and 150 amino acids.
* The presence of anomalous scattering atoms. This could be one or more
sulphur atoms from cysteine or methionine residues or heavy atom derivatives
from the native protein or better, MAD synchrotron data.
* hkl-Recording from the complete 'Ewald-sphere' or as complete as possible.
Therefore including equivalent and/or 'Friedel' reflections.
* A data-set from as high as possible resolution. Here I will probably force
an open door, because protein crystallographers always want as high as
possible resolution data.
The X-ray data-sets will be used for testing and developing new Direct Methods
so the elucidation of new protein structures will not be the first goal. Even
solved proteins are more desired for my research at this moment in relation to
If you can help me with suitable data-sets, please contact me at the address
