FeoA has an SH3-like domain; the FeoB GTPase activity is stimulated 5-fold by KCl and is not stimulated by FeoA addition (Lau, 2013). The FeoA role in ferrous iron uptake is undetermined, but a requirement was demonstrated by Taudte, Ph.D. thesis, 2003, Martin Luther University, cited in (Grass, 2006). Fur regulon. FNR regulon.
