Reversible DNA condensation drives natural transformation

Joshua I. Santiago, Ishtiyaq Ahmed, Jeanette Hahn…·Keith J. Mickolajczyk

This study shows ComEA reversibly condenses DNA during natural transformation, first pulling DNA into the periplasm and then promoting its transport into the cytoplasm.
