Abstract:DR0248 is a protein identified in the Deinococcus radiodurans (DR) genome that is predicted to encompass two domains: an N-terminal minimal nucleotidyl transferase domain (MNT) and a C-terminal higher eukaryotes and prokaryotes nucleotide-binding domain (HEPN). These two domains, usually encoded in two ORFs, have been suggested to play the role of a toxin-antitoxin (TA) system in prokaryotes. Recombinant DR0248 was overexpressed and purified from Escherichia coli and diffraction-quality crystals were obtained … Show more
