Hi,
Lattice-translocation disorder is one possibility.
How does the diffraction image look like?
Are there any streaks?
Best regards,

Dear all,
we are currently in the process of solving the structure of a Fab/peptide
complex. We have first determined the structure of the native Fab and refined
it to ~2A, so we have a decent MR model. The complex crystals that we are
working on right now diffract to ~3.2A and are
Dear All:
I try to solve a structure by using Phaser.
The data set was collected at 3.9 A with 98.1% (95%) completeness. Based on
pointless, the best space group for the data set is P21212. And the data
can be processed with P21, P212121 as well. The I/sigma value for the data
is 13.3 (1.9).
Hello CCP4bb
I am solving a 3.2A resolution crystal data for a protein DNA complex.
I would like to know-
1) How to validate the DNA constraints in the crystal structure?
2) How to fit DNA into density? How different it is from protein fitting
into density?
3) What kind of parameters to consider
Dear Thomas,
At the moment, Phaser only deals fully automatically with 2-fold tNCS (i.e. one
unique peak in the native Patterson), although we’re hoping to make it more
general. With some tailored input, it can also deal with the case of several
copies related by multiples of the same NCS
HI, Mark:
Thank you for your suggestions.
try all possible spacegroups with PHASER
Yes, this is done with all the modeling.
make sure you are using a monomer as search model
I also tried with monomer as search model. When run with refmac5, the
R-value is above 0.5.
I exam the model in coot.
