This domain is found at the C-terminal of FecR [1,2], which adopts a secretin N0-like fold [1]. FecARI are responsible for induction of the ferric citrate uptake system. When ferric citrate binds FecA, a signal is transmitted across the outer membrane to FecR, a cytoplasmic membrane protein that transmits signal across the membrane and activates the sigma-70 family protein FecI [2].
