The ATP synthase operon atpBEFHAGDC is important since it provides ATP to the cells. We prove that the expression of this operon in Corynebacterium glutamicum is controlled by the sigma factor sigH. The purification of the SigH protein and its binding to the ATPase promoter sequence, confirmed by EMSA, proved this regulation. Besides, the sigH binding sequence has been defined.
