[ccp4bb] Fwd: [ccp4bb] Calculate dipole moment of ligands from their coordinates

2008-01-28 Thread Miguel Ortiz-Lombardía
Hi all,

For those interested, this script can be downloaded from:

http://www.ysbl.york.ac.uk/~mol/scripts.htmlhttp://www.ysbl.york.ac.uk/%7Emol/scripts.html

There is a short description as well. It works with proteins and molecules
for which you can generate partial charges in a force field supported by
pd2pqr.

It produces a bild object that can be loaded in the program Chimera from
the UCSF. But it can be easily re-written to produce output for other
graphic programs. Feel free to do it!

Cheers,


Miguel

2008/1/26, Miguel Ortiz-Lombardía [EMAIL PROTECTED]:

 Hi Zheng,

 I have python script that does so if you have the program 'pdb2pqr'
 installed (http://pdb2pqr.sourceforge.net/)

 Let me know if you're interested.

 Cheers,


 Miguel

  Hi, All
 
  Sorry about non-CCP4 questions. It is the best board I find so far to
  learn stuff related to structure biology. Could anyone suggest me any
  program that calculates dipole moment of a ligand from its coordinates?
 
  Thanks, sorry to bother others.
 
  Zheng

[ccp4bb] Format convertion ccp4 to spider

2008-01-28 Thread francesco zonta
Goodmorning. I need to convert a file form ccp4 to spider or situs format.
The only programs I found to do this task are em2em and map2map (in the
situs package). But both of them seems not to work.
Do someone knows if any other program exists for converting files?

Thak you very much.

[ccp4bb] Postdoctoral positions in Protein Crystallography, Glasgow

2008-01-28 Thread Frank Kozielski
Postdoctoral Positions in Protein Crystallography at the Beatson Institute for 
Cancer Research, Glasgow

 

We are seeking several highly motivated postdoctoral researchers to investigate 
the structure of cancer related proteins and drug targets.

 

We are a newly established group at the Beatson Institute for Cancer Research 
in Glasgow, UK. Our group is interested in proteins of the kinesin superfamily, 
and their associated proteins, with a focus on human mitotic kinesins. Many of 
these proteins are good candidates for drug development in cancer chemotherapy. 
In addition, we will also determine the structures of other cancer-related 
proteins in collaboration with other groups in the Institute.

 

We have a new, fully equipped and state-of-the-art structural biology 
laboratory including ÄKTA protein purification systems, nano- and micro-drop 
robots for automated protein crystallization, a Rigaku HighFlux Homelab 
microfocus diffraction system and comprehensive data processing facilities. In 
addition, we are well equipped to characterise the biochemistry of protein - 
inhibitor complexes towards the optimisation of lead compounds in collaboration 
with our chemist colleagues.  The Beatson Institute has a large range of core 
service facilities including DNA sequencing, protein production and mass 
spectrometry.

 

A number of positions are available (3 year contract in the first instance):  

 

1) We require researchers with significant experience in protein 
crystallisation and structure determination and who are fully familiar with all 
the major software packages for x-ray crystallography.  

 

2) An additional post is available for a biochemist with experience of 
characterising protein-inhibitor complexes. Experience in data processing, 
structure solution and model building is required. 

 

3) The third position requires experience in cloning, expression and 
purification of proteins. The successful candidate is expected to actively 
participate in structure determination. Experience of crystallisation robots is 
an advantage but not essential.

 

Closing date for applications is 22nd Feb 2008.  Applications, with CV and 
names of three referees, should be sent by email to:

 

Prof. Frank Kozielski

Re: [ccp4bb] Format convertion ccp4 to spider

What sort of file? Coordinates or reflections or map?

Look at the GUI - reflection utilities or coordinate utilities and see 
if it offers what you want?

[ccp4bb] New versions of Mosflm and iMosflm

2008-01-28 Thread Harry Powell

Hi folks

We are pleased to announce updated versions of Mosflm (version 7.0.2) 
and iMosflm (0.6.0).


If you upgrade iMosflm, you should certainly upgrade Mosflm at the same 
time; there are many changes which depend on both parts being in sync.


The main change is that we have a new developer for iMosflm; Luke 
Kontogiannis ([EMAIL PROTECTED]) has been with us since October 
and has been very busy implementing improvements to iMosflm, so that it 
is now more robust and even easier to use.


Most of the changes to Mosflm itself are involved with bug fixing and 
improved communications with iMosflm, so you shouldn't notice a lot of 
difference.


Changes to Mosflm since 7.0.1

 * New detectors - Mar555 Flat Panel. Pilatus miniCBF images 
added.
 * Better support for Bruker 100 Format images (converted with 
frm2frm).

 * Change IP address for communication with iMosflm to the loopback
   address (127.0.0.1 or localhost).
 * Rectangular non-square detectors added for output to iMosflm 
display.
 * Bug involving R-Axis detectors writing d*Trek style headers 
fixed.
 * Many small bugs fixed - many thanks to all those who gave us 
feedback, especially

   Clemens Vonrhein  Jim Pflugrath.

Changes to iMosflm since 0.5.3

 * Resizeable image display by dragging the window edges
 * Ability to delete sectors in the image selection panel by 
right-clicking

   on selected sector
 * iMosflm correctly deals with datasets where the first image has 
an index
   of zero. The batch number is offset to 1000 and the processing 
and writing

   out of the mtz file proceed normally
 * The spotfinding summary pane in the indexing panel now shows the 
number

   of spots with an intensity greater than the I/sigI threshold
 * Ability to stop the log file view autoscrolling with 
Control-UpArrow key

   combination. Resume autoscrolling with Control-DownArrow
 * Search the log file by bringing up the search panel with 
Control-F key
   combination. Control-F searches forward and Control-G searches 
backwards

[ccp4bb] Crystal Screening and Analysis web server

2008-01-28 Thread P Hubbard

Hi All,

I've rewitten the code for the Crystal Screen Wizard web server. The original 
aim of this home project was to analyze drop appearance patterns from initial 
screening in order to find ideal storage buffers for unstable proteins; 
however, I've modified it to include other useful features for things such as 
cataloging crystal optimization trays. The new server can do the following:

1) Using simple point-and-click options, produce extensively annotated graphics 
of your crystal trays (screens and optimizations) which can be cut and pasted 
into your lab book/computer file.

2) Handle 24 and 96 well plates.

3) Allow one to select multiple drop appearance types for each condition for 
analysis.

4) Analyze all possible drop appearance types for common agents simultaneously.

5) Using a crystal screen, analysis now gives the user a quick summary of what 
general salt and pH conditions the protein appears to like/dislike.

I will include a simple salt crystal predictor and ionic strength estimator in 
the near future.

Please feel free to e-mail me any comments, report bugs, or suggest 
improvements.

P.S: Old users, please note the change of the domain name.

Cheers,
