Anti-sigma-28 factor flgM FLGM_YEREN 99 Responsible for the coupling of flagellin expression to flagellar assembly by preventing expression of the flagellin genes when a component of the middle class of proteins is defective. It negatively regulates flagellar genes by inhibiting the activity of fliA by directly binding to fliA (By similarity).
