^aBased on CGH data
^bCongo-red binding
^cMotility on LB plates, average of four plates. '-', non-motile; '+', average motility; '++', high motility (i.e. covered the whole plate, 80 mm)
^dSame results were obtained with and without mannose
^eMedium signal intensities were observed for this strain, i.e. that it cannot be excluded that it carries a divergent version of this operon
^fThe reason for this discrepancy remains unknown.
