This domain is found at the C-terminal end of Nucleoid occlusion factor SlmA from Escherichia coli and similar transcriptional repressors from proteobacteria. SlmA is required for the nucleoid occlusion (NO) phenomenon, which prevents Z-ring formation and cell division over the nucleoid. It is organised into two domains, a small N-terminal Pfam:PF00440 and a C-terminal domain (this entry). This domain shows an all-alpha configuration. This region mediates dimerisation [1].	Domain
