PROTEIN CRYSTALLOGRAPHY STATION AT LANSCE -- CALL FOR PROPOSALS

Crystallography Station (PCS) at the Los Alamos Neutron Science Center. The
I have battled a similar piece of structure in a recent project. There
is no software in crystallography that can handle hierarchical alternative
conformations w/o tricks. I was refining in Shelxl but the same trick
will work elsewhere. I had to define a new residue type, with two heads.
The
I am currently trying to refine a structure where a 5 residue stretch of a
chain is in 2 conformations. Oddly enough, 1 of these 5 residues is in dual
conformations in both the conformations! Is there a conventional nomenclature
for defining such dual-dual conformations?
Refmac5 does not accept
A postdoctoral position is available in the lab of Filip Van Petegem at the
University of British Columbia.
Our lab focusses on calcium channels in both the plasma membrane and
intracellular compartments. Calcium is an important 2nd messenger and
channels allowing influx of calcium into the cytop
The problem was fixed. I changed the original RgbPath in /etc/X11/xorg.conf
from "/usr/X11R6/lib/X11/rgb" to "/usr/share/X11/rgb". I can now run ccp4i.
Thanks everyone for pointing it out.

At first glance I thought it looked like a problem with the CCD detector
overloads, but that apparently has been ruled out.

Hi All,
I just downloaded and installed ccp4 in my home directory. The installation
went quite smoothly. For individual ccp4 programs, it seems working ok.
however, when I type ccp4i, it gave a bunch error message. here are the
error message:
Top level CCP4 directory is /home/X/programs/ccp4-6
ClearSeal film from Hampton works with our UVEX UV microscope, despite some
attenuation of UV light.
For hanging drops, Greiner BioOne's films are the best.

Dear colleagues,
I am having the pleasure to organise a shipment of frozen crystals from

Germany?) done this before and give me som

Hi,
Can anyone recommend any UV-transmissible (280 nm), adhesive seals
(pre-cut) for 96-well crystallization plates (Greiner, MRC)?
We would like to use them on an crystal imaging system with UV option
(RIGAKU). I've checked seals from Zymark/Calliper Lifescience with a

With good 2.0 A data (as you seem to have) and a correct solution,
