3. The structure factors are lower for large unit cells. This will mean they
will be harder to detect, particularly if there is a high background.

Hi Guys,
I just want to make aware that apart form PRODRG etc there exist also PURY
server http://pury.ijs.si/, which offers a possibility to create restraints for
heteromolecules. It accepts PDB files, smiles format. Alternatively JME
editor can be used to draw your compound.

Hi everyone,
I have crystals of a protein of 176 residues, with 5 Cys, 8 His, 3 Met.
Native crystals grow in 10% MPD, 100mM Bicine pH 9.0. They show a nice
diffraction, but appear to be perfectly twinned.
I have crystallised a SeMet derivative, but I have not been able to
collect sufficiently

Does anyone have any experience with formation of crystals of dodecyl maltoside
in the presence of PEG?

What exactly is your question--I saw tons of crystals of DDM and
PEGs, I think especially P400, if I recall correctly.

You can use Phenix.elbow or phenix.reel to load the coordinates of the

get reasonable geometirc parameters suc as bond length, bond angles and

Hope this helps !
Cheers,

Yes. Equating the square root of the measured intensity (photons/spot) to the
structure factor was sloppy nomenclature on my part.
One should look at Darwin's formula for the intensity (photons/spot). The
adverse term in it is Vxtal/Vcell (ratio between crystal and cell volumes).
They show a nice diffraction, but appear to be perfectly twinned.
In most cases, structures can be solved (and biological questions answered) in
twinned cases. I wouldn't be discouraged.

sufficiently good data, to

Dear All,
For the RCSB depositation report, it gives the Average Occupancy-weighted avg
temperature factor (Deviation).
Will you please tell me what range the Average Occupancy-weighted avg

value?
