I just want add that the redundant PDB got a new site http://pdbflex.org/ (It's pretty cool actually) Thanks to Robyn for pointing that out. El dom., 22 de sep. de 2019 a la(s) 10:18, Robyn Stanfield ( ro...@scripps.edu) escribió: > Hi, > > The Burnham changed names sometime back, that may be

@Jarva: I was looking for something like your distribution. I would very much like to know how did you get the data? Can you show us (or me)? Please. I would like to play with it. Same to @Mesters, how do you get that list? PS @Waterman I agree with you, it is a problem. @Everybody: Thanks for

archive.org suggests the database existed up to December 2018, but appears to be no more. What to do when scientific resources associated with published papers disappear like this? It seems to be a problem that is not very well addressed. Cheers David On Fri, 20 Sep 2019, 04:26 Murpholino

As far as lysozyme is concerned, the space group obtained is mainly the result of an interplay between the pI of lysozyme on the one hand and the pH of the solute and type of salt (or organic small molecule) on the other hand (Hofmeister series). The pI is about 9.5 and one should not be

Following my last question I was searching for a redundant PDB and found this paper https://doi.org/10.1016/j.str.2007.07.012. I went to the methods section and found out that the link to the database of redundant protein structures is now gone (http://dper.burnham.org/). Anyone knows of a similar

My recollection is that gamma-chymotrypsin crystals will persist in pHs all the way from 3 to 9. I don't know if the crystals will grow over that range. There are a fair number of phage T4 lysozymes variants in the PDB. I don't think this is considered "overpopulation" but a valuable

A quick glance at the entries of hen egg white lysozyme in the PDB show that it can be crystallized at different pH values, but the space group is not always the same. I still have to refine the analysis but I was wondering that maybe there are a few proteins that can crystallize at a wide range
