DNA‐processing protein A, a ubiquitous multidomain DNA‐binding protein, plays a crucial role during natural transformation in bacteria. Here, we carried out the structural analysis of DprA from the human pathogen Helicobacter pylori by combining data issued from the 1.8‐Å resolution X‐ray structure of the Pfam02481 domain dimer (RF), the NMR structure of the carboxy terminal domain (CTD), and the...
The ComD–ComE two‐component system controls the competence state of Streptococcus pneumoniae via the phospho‐regulation of ComE, which fluctuates between monomeric and dimeric states. We previously showed that the non‐phosphorylatable ComED58A mutant is monomeric in solution, whereas the ComED58E active mimic mutant dimerizes via its REC domains. The crystal structure of ComED58A revealed an asymmetric...
