Hybrid Exb/Mot stators require substitutions distant from the chimeric pore to power flagellar rotation

P. Ridone, M. A. Baker

The paper designs and tests chimeric ion-powered rotary motors (IRMs) by combining components from different bacterial systems, showing that functional improvements require substitutions outside the hybrid pore region.
