9.A.8.1.1 Ferrous iron uptake system, FeoAB. FeoB is the main transporter while
FeoC is a transcriptional regulator. FeoA has a Src-Homology (SH3)
domain (a β-barrel with two overlying α-helices) plus two extra α-helices
not usually found in SH3 domains. FeoA interacts with the
cytoplasmic domain of the conserved core portion of the FeoB
transmembrane region, but may not function as a GTPase activator as
previously proposed (Lau et al. 2012). FeoB transports Fe(II) from the periplasm to the cytoplasm, but the C-terminal domain can also bind Mn2+ and Zn2+ as well (Orzel et al. 2023).
