Hi all,
While reading a crystallographic paper describing the structure
of an apo-protein and its complex I noticed that
the authors described the space goup as P6122 for the unit cell:
a=141.9, b=143.9, c=380.4
Yes; a==b for P6i - prob. a typo..
B factors at 3.2A are hard to fix - it will depend on scaling convention
to some extent..
Can you download the data and re-run refinement for your own satisfaction.
If R ==Rfree for the complex then I suspect they did not transfer the
FreeR flags from the
Hi!
Your problem is probably this: you don't have 3 domains. You have 3 NCS
copies, but only 1 domain.
In CCP4I, instead up using the 'Add domain' button to add new operators,
you should be using the 'Add operator' button.

Hi All,
Thanks a lot for all reply with valuable inputs. In my original
post: I meant a = b does not equal c. I used # for does not equal.
Many asked where is that paper published! Actually the paper is
under revision. When reading, I assumed the unit cell dimensions (or
the space
You have a good point there and I would be interested in hearing
some other opinions, so I take the liberty of reposting-
My instinctive preference is that each structure should be
supported solely by the data that is deposited with it -
(one dataset one structure) but in terms of good science
Wouldn't the desirability of this depend on the extent to which the
molecule has moved between the high-resolution and low-resolution
datasets ? I would have thought that there was an effective information
transfer between R-work and R-free once the rigid body movements became
too large,
Dear structural(-ly interested) biologist !
HIC-Up, the Hetero-compound Information Centre - Uppsala, has been updated and
now contains information on 7,452 hetero-entities. This is the last HIC-Up
version prior to the release of the remediated PDB. Hopefully, the remediation
will improve the

I have a question about how to show certain h-bonds with CCP4MG. I¹d like to
show a specific bond between an Arg and Glu, but not other H-bonds made by
the Arg. How can I do this?
Thanks!
