A stem-loop mutation between ccpA and motP in the Bacillus subtilis ccpA-motPS operon increased motPS transcription and membrane-associated MotPS levels, motility, and number of flagella/cell when MotPS is the sole stator and the MotPS contribution to motility at high pH, Na+, and viscosity when MotAB is also present.
