Dear all,
I would like to draw your attention to a postdoc position at AstraZeneca
(Cambridge UK) in collaboration with Prof Ashok Venkitaraman's group at the MRC
Cancer Unit. This is an opportunity for a talented and self-motivated
structural biologist to undertake biophysical and cryoEM studi
sessions about biophysics,
crystallography and cryoEM.
If you have an exciting scientific story to share in form of a talk (especially
on HDX and degraders), please feel free to get in touch with the organisers:
Judit Debreczeni (judit dot debreczeni at astrazeneca dot com) or Chris

To give a short practical rather than a lengthy philosophical answer:
- in real space: you can try Ramachandran restraints or secondary structure
restraints -- indeed, both can be switched on in Coot in the refinement and
regularisation parameters window (R/RC button in the top right corner). Or
Your solution sounds good. However, another way to skin this cat could be to
define the unnatural residue as an amino acid residue and link it up to the
other amino acid residues using the standard peptide bond description -- which,
I believe, should be picked up automatically if the unconventio

Does your kinase autophosphorylate by any chance? -- That can produce
differently phosphorylated species and affect crystallisability. You can
detect it by e.g. mass spec, and tackle it by dephosphorylating the
protein prior to crystallisation or by coexpression with a phosphatase.

Hi Krisztian,
I have seen refmac fall over in a similar situation (low-ish res,
partially floppy model) during TLS refinement. You could try to rescue
it by
- using fixed TLS parameters from a previous (successful) refinement
- setting initial B-values to a fixed value
- including the peptide in o
DM is kind of past tense (unless you are dealing with multicrystal averaging)
-- I'd use parrot or shelxe instead (both pretty fast and automated). NCS
operators as input do not seem to be in fashion these days, so you might have
to put up with heavy atoms or partial MR models...
I would not

IIUC, you would like to keep the distance between the ring plane and the Ru
fixed and allow the ring to rotate freely.
I would define bond length restraints between each of the ring atoms and Ru (I
suspect that these distances will be the same for each atom pair) -- the ring

Also, if you happen to use refmac for refinement: it rewrites LINK
records as LINKRs in the output pdb file -- and LINKR records are
unknown to Coot...

I've seen flattening of the C1 atom recently in Coot - in that case the reason
was that, as the density wasn't really clear around the sugar, I'd fitted it
180 degrees rotated around the ASN-ND2---C1-NAG bond. In such cases Coot
happily flattens the sugar ring such that C1 C2 C3 C5 O5 are in a p

It should be something like:

Dear all,
I am looking for the sugar-validation tool pdb-care -- the
glycosciences.de website seems to be down, sadly.
Are pdb-care and the other rather valuable glycosciences tools available
somewhere else? I'd prefer to run them locally -- are they available as
stand-alone applications?
Hi,
if you feel you are good at _chem_link sections of dictionary files (and know
how refmac understands them), please read on.
My question in short:
what is the Right Way of defining a covalent link between a ligand that is not
in the standard refmac library and a standard amino acid residue,

Dear all [mmdb users and authors],
I've upgraded to Fedora 9 and now I'm trying to build coot which also
requires mmdb. Now, F9 comes with gcc 4.3 which seems to be
incompatible with mmdb (I think I'm using mmdb-1.0.8) as it gives many
hundreds of the following (and others):

In Coot (0.3.2 and later) you could also try the following:
- center on the serine to be phosphorylated
- click Extensions->Phosphorylate this residue
and Coot will sort out phosphorylation, renumbering etc in no time.

Unreasonable geometry can be avoided by setting the refinement weight to a
lower value -- either using Extensions->Set Matrix (Refinement Weight) or in
your .coot file:
(set-matrix )
There's also a coot-bb, btw.
