Abstract

Flagellation in archaea is widespread and is involved in swimming motility. Here, we demonstrate that the

structural flagellin gene from the crenarchaeaon Sulfolobus solfataricus is highly expressed in stationary-phasegrown

cells and under unfavorable nutritional conditions. A mutant in a flagellar auxiliary gene, flaJ, was

found to be nonmotile. Electron microscopic imaging of the flagellum indicates that the filaments are composed

of right-handed helices.
