3.A.1.14.7
Iron (Fe3+)-hydroxamate porter (transports Fe3+-ferrichrome and Fe3+-ferrioxamine B with FhuD1, and these compounds plus aerobactin and coprogen with FhuD2).  FhuB may function with FhuG (A6QEV8) together with FhuD2 to form a ferrichrome transporter where FhuB and FhuG have conserved arginine residues (R71 and R61, respectively) that form essential salt bridges with FhuD2 (Vinés et al. 2013).
