Dear Vito
I looked at the examples of I3C in 3e3d, 3e3s and 3e3t and certainly the latter
two show clear 2Fo-Fc for several I3Cs at a range of occupancies. So my mention
of the different difference maps’ effectiveness does not apply.
Hermann and Eleanor suggestions hopefully will explain your

The Rmerge in the strong intensity bin of 0.079 is untypically high it seems to
me.
Were the diffraction images underexposed?

You could try reindexing into P1, then run Phaser and with its solution as
input to Zanuda determine the space group.

Hello Harry
I used SRS 7.2 and 9.6 at a wide variety of monochromatic wavelengths for
resonant scattering (AD) studies. But I can imagine high intensity application
PX measurements were made at those specific wavelengths which you mention.

Dear all,
I have a (heavily and heterogeneously) glycosylated protein that has very low
OD280 absorption. I wondered whether the glycans will have any effect on the
accuracy of BCA or Bradford assay. Amino acid analysis doesn’t seem to be any
better because carbohydrates will interfere with
Dear CCP4 members,
I’m working on a phosphocholination pathway in which the enzyme utilizes the
substrate Cytidine-diphosphate-choline (CDP-choline) as phosphocholione-donor.
I’m enquiring about the possible analogs of CDP-choloine for
cocrystallization with the enzyme as well as for the
Dear George
My student class would not find that IUCr dictionary definition helpful. What
they do find helpful is to state that they cannot contain an inversion or a
mirror.
To honour Sohnke is one thing but is it really necessary as a label? You're

them? Maybe students would not be as refractory to the idea as might first
be thought.
With best wishes,

Hi Afshan,
Have look at http://www.douglas.co.uk/Scaling_Up.htm, Patrick has some
general tips on scaling up. Elsewhere on his site you'll find tips for
conversion to microbatch, you may want to try that out as well. I assume
the screen crystals were not big enough to mount?

No matter what we tried, we could not get convert2mtz (or any other program) to

What you did not indicate is if your lack of diffraction was of frozen

It sounds like list your GST construct is not binding to the column
(or very well) when the peptidase is attached. GST needs to form a dimer
to binding to the column - I suspect that your construct interferes with
dimer formation - when the peptidase is present, but when not there due
