Comprehensive genetic dissection of the magnetosome gene island reveals the step-wise assembly of a prokaryotic organelle
TL;DR: A comprehensive functional analysis of the MAI genes in a magnetotactic bacterium, Magnetospirillum magneticum AMB-1, shows that magnetosomes are assembled in a step-wise manner in which membrane biogenesis, magnetosome protein localization, and biomineralization are placed under discrete genetic control.
Journal ArticleDOI
Synthetic Riboswitches That Induce Gene Expression in Diverse Bacterial Species
Shana Topp,Colleen M. K. Reynoso,Jessica C. Seeliger,Ian S. Goldlust,Shawn K. Desai,Dorothée Murat,Aimee Shen,Aaron W. Puri,Arash Komeili,Carolyn R. Bertozzi,June R. Scott,Justin P. Gallivan +11 more
TL;DR: A series of ligand-inducible riboswitches that control gene expression in diverse species of Gram-negative and Gram-positive bacteria, including human pathogens that have few or no previously reported inducible expression systems are developed.
Journal ArticleDOI
The magnetosome membrane protein, MmsF, is a major regulator of magnetite biomineralization in Magnetospirillum magneticum AMB‐1
Dorothée Murat,Veesta Falahati,Luca Bertinetti,Roseann Csencsits,André Körnig,Kenneth H. Downing,Damien Faivre,Arash Komeili +7 more
TL;DR: A new biomineralization protein is defined and the foundation for the design of autonomous gene cassettes for the transfer of the magnetic phenotype in other bacteria is laid down.
Journal ArticleDOI
Cell Biology of Prokaryotic Organelles
TL;DR: This article highlights some of the prokaryotic organelles and discusses the current knowledge on their ultrastructure and the molecular mechanisms of their biogenesis and maintenance.
Journal ArticleDOI
The HtrA/DegP family protease MamE is a bifunctional protein with roles in magnetosome protein localization and magnetite biomineralization.
TL;DR: Results imply the existence of a previously unrecognized ‘checkpoint’ in biomineralization where MamE moderates the completion of magnetite formation and thus committal to magneto‐aerotaxis as the organism's dominant mode of navigating the environment.
