I think it is worth reporting/publishing this crystallization and structure in addition to depositing it in the PDB and ContaMiner/ContaBase databases. Items you can consider in reporting it based on the following but can take a better decision if you complete the structure to deposition quality:

Hi Mohamed, I don't recall such a case of a crystallized proteolytically cleaved contaminant (see our recent summary of contamination cases http://scripts.iucr.org/cgi-bin/paper?ei5009 , and references therein). I would certainly recommend depositing the data at the PDB - it may help others address

This may seem an interesting case, given that protocol fur purification, and subsequent crystallization is reproducible as well as this enzyme is a valid drug target for pathogenic strains of E. coli. Best Z On Apr 5, 2017 02:51, "Vipul Panchal" wrote: > I don't think it is going to be any scien

I don't think it is going to be any scientific story. Even if you think of publishing what aspect are you going to discuss? What new are you going to give to the community. On Wed, Apr 5, 2017 at 2:46 AM, Mohamed Noor wrote: > During the crystallization of a totally unrelated protein from a diff

During the crystallization of a totally unrelated protein from a different bacterium in E. coli, we managed to somehow crystallize an E. coli protein. It turned out to be only the catalytic domain of an enzyme. Two previous reports both used recombinant expression of this enzyme followed by limi
