Crystallization Contaminants
A list of crystallization contaminants deposited in PDB that we (plan to) use for quick screening.
It's mostly based on a list from E. Niedzialkowska et al. and a list from the ContaMiner project.
We are grateful to the authors for compiling neat lists. Previously, the usually referred to resource was this summary from ccp4bb (2010). Both lists focus on protein domains for molecular replacement.
Here, we're also interested in quick screening based on the unit cell parameters.
We process this page automatically
reading UniProtKB entry names and going:
UniProtKB entry ⇨ UniRef clusters ⇨ a set of PDB entries ⇨ filtering ⇨ clustering (complete-linkage) by space group and unit cell.
(We also read PDB IDs below to handle the case when they are not included in the SIFTS mapping.)
Finally we get this list of distinct unit cells.
Do you see something missing in the list below? Feel free to edit it (you should see the [Edit] button when logged to GitHub). Or email wojdyr@gmail.com. Or contact authors of the two lists above.
