1.B.14.1.20
The iron-citrate receptor/transporter, FecA.  TonB mediates both signaling and transport by unfolding portions of the transporter (Mokdad et al. 2012). The ferric citrate regulator, FecR, is translocated across the bacterial inner membrane via a unique Twin-arginine transport dependent mechanism (Passmore et al. 2020).
