[ccp4bb] Fwd: [ccp4bb] Radius of Gyration

2008-10-29 Thread Nathan Cowieson
I know it's not CCP4 but I use moleman2 for this, http://xray.bmc.uu.se/usf/xutil.html . You read your pdb into moleman and choose the STatistics option, it outputs Rg among lots of other things. It can all be scripted too if you wanted to say charge through the whole PDB and get Rg for ever

Hallo, one and all, I was wondering if anyone knew of a quick method (say, a publicly-available script, or subroutine in a CCP4 program) by which one might calculate the Radius of Gyration of a molecule, given its pdb file. Any ideas? Many thanks, Dave Shechner Graduate Student Bartel Laborator

[ccp4bb] PEG degradation/properties lit source

2008-10-29 Thread Jack Tanner
We had a similar experience a few years ago. In our case, the adventitious ligand was L-lactate, which happens to be a competitive inhibitor of our enzyme. We used using L-lactate dehydrogenase assays to show that several commercially available PEGs contain L-lactate. We also think that acetate

Hello,   I would greatly appreciate anyone who would know of a basic literature source on the properties of PEG and particularly on PEG decomposition or degradation products.  We see densities in our maps  for ethanol molecules, but our condition for the crystals do not have added ethanol.
