-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 The Protein Geometry Database looks at proteins as collections of bond lengths, angles, and torsion angles. It is not the place to go when you want to know how a protein part is related in space to some other (covalently) distant part. Andy

2014-06-30 Thread Herman . Schreuder
Dear Bernard, we once worked with a series of protease inhibitors which turned out to be slow substrates, e.g. an acyl intermediate was formed that was subsequently hydrolyzed. Here we had to reduce the soaking times to below 30 minutes, otherwise we would see nothing, e.g. the large excess of

[ccp4bb] a warning message from XDS (IDXREF)

Hi all, I use XDS to process a data set. When I checked the log files I found a warning message at the end of IDXREF (as below). What should I do next? How to judge which solution is correct? !!! WARNING !!! SOLUTION MAY NOT BE UNIQUE. OTHER POSSIBLE SOLUTIONS CAN BE TRIED IN THE CORRECT STEP

Nothing to get worried about. It means that other, equally valid choices of axes may be possible (e.g. with polar space groups). Only if you want to merge data from different crystals or if you want to scale native and derivative data, you have to make sure that the same choice of axes is being

For free: After 16 years of service our home source is retiring. It is an FR591 Rotating anode generator. The anode motor needs replacement (estimated cost 4-5000 €) but otherwise the generator is functional. The generator can be picked up for free. Not for free: In 2005 the generator was

[ccp4bb] WAXSiS: New web server for SAXS/WAXS calculations based on explicit-solvent molecular dynamics

Dear SAXS and crystallography communities, it is our pleasure to announce a new web server for the calculation and fitting of SAXS/WAXS curves of biomolecules in solution. WAXSiS (WAXS in Solvent) computes SAXS/WAXS curves based on explicit-solvent all-atom molecular dynamics simulations. The

Jacob Keller There is a service that will hopefully do the calculation you want, search for a template of residues (eg. catalytic-triads). This is just a through space superposition of atoms. It is part of a tool set of fragments found by knowledge based analysis (pdbetemplate)

Hi everyone, I have two questions: 1- I was trying to run the program Acorn, on a SAD dataset (Se derivative) that was scaled in scalepack/HKL2000. converted to .mtz using scalepack2mtz, then edited in REVISE and Ecalc. But when I ran Acorn it gives me the error message Segmentation fault. Does
