Research Article | Molecular Biology and PhysiologyThe Polar Organizing Protein PopZ Is Fundamental for Proper Cell Division and Segregation of Cellular Content in Magnetospirillum gryphiswaldenseMagnetotactic bacteria (MTB) share the unique capability of magnetic navigation, one of the most complex behavioral responses found in prokaryotes, by means of magnetosomes, which act as an internal compass. Due to formation of these unique nanoparticles, MTB have emerged as a model to study prokaryotic organelle formation and cytoskeletal organization in conjunction with complex motility systems. Despite the high degree of subcellular...
- Research ArticleA Screen for rfaH Suppressors Reveals a Key Role for a Connector Region of Termination Factor Rho
The transcription termination factor Rho silences foreign DNA, reduces antisense transcription, mediates surveillance of mRNA quality, and maintains genome integrity by resolving transcription-replication collisions and deleterious R loops. Upon binding to RNA, Rho undergoes a rate-limiting transition from an open “lock washer” state to a closed ring capable of processive translocation on, and eventually the release of, the nascent...
