Hi all,
You can find our release policy in the chapter 2 of "Annotation
Policies" document which is available from the following URL.

We encourage all the PDB depositors to carefully check the journal
policy for the availability of coordinates (and experimental
I only deposited the high-res apo coordinates, but pdb code 2AU3 was solved
from a thulium soaked crystal. In fact, I also used dysprosium to phase
primase from a different bacterium. Go team lanthanide!

Hi People,
Could anyone point me to successful examples for two unrelated
proteins that have been stitched together into one single polypeptide
chain with flexible amino acids to create a functional chimera that
was subsequently crystallized. I've looked up a few.

Very old trick from the stone age of crystallography.
Long time ago ~ 1999 I cryoed one crystal with 1.5 M hexanediol but
there was also 10% glycerol around.

Some more info about this structure:

This does not sit on any crystalllographic symmetry axis.
But it sits right between two monomers and the NCS 2-fold axis.
The protein is chemotaxis protein CheX.

My money is on:
Dithiothreitol or dithioerythritol.
Any chance they are in there? If not and you believe this copurified with
your protein, than I'd guess erythritol or threitol.
(I didn't bother trying to gauge the stereochemistry from your picture)
Cheers

Hi,
I am refining a structure and have a region of unmodeled density into
which I am trying to fit a ligand. The identity of the ligand is not
obvious, so I modeled a bunch of dummy atoms into the density.
Could you please have a look at the map and pdb files and help me
identify this ligand?
I do not mind PDB releasing only on Wednesdays at a certain time of the
day. What should happen is the authors/publishers should let PDB know
the publication date before it becomes available (supposedly days or
weeks before the actual publication, online or in print), and PDB can

PDB seem to take about a week to release coordinates that are HPUB (hold
for publication) from when we ask them to. Sometimes they drop the
ball, but mostly this is what we see. If I ask them to release the
coordinates early to get around this lag, I can largely guarantee that

I agree that the pdb deposition process has gotten better, but I still

A standard orientation is anything you want it to be and is usually
defined in the context of orthogonal axes. It is simply a reference
point from which you apply the results of your search. We usually
use one or more of the orthogonal axes as a starting point for easier
visualization.

Dear ccp4bb,
I'm trying to update Tcl/Tk on a mac running OSX5.6 as my version of
mosflm has suddenly started crashing when trying to autoindex, so I
figured the best thing to do was to reinstall both mosflm and its
dependencies.
So I went to the CCP4 download page and used the Daresbury

I guess it depends on your criteria for success. We made a successful MR using
data to 8Å with a search-model with 20% identity covering 90% of the target. The
resultant phases gave a map where a few new 'blobs' could be observed. Not very
useful, but the MR-phases could be used to solve the HA
Hello Peter,
at 3A resolution occupancy refinement is supposed to fail, I'd say.
The large B-values can make up for reduced occupancy (as you already
pointed out to) but also large flexibility.
You might try ten refinement runs in parallel with fixed occupancies
varying from 10% to 100% and c
Peter from you description seems that big blob is not your ligand. In 3.0
resolution molecules with similar size, including ligands, tend to look
similar in shape as well. I suggest you refine further your structure and
check again later this N-terminal blob of density. It may tern out to be a
bias
