Publication Abstract from PubMedThe FeoB family proteins are widely distributed prokaryotic membrane proteins involved in Fe(2+) uptake. FeoB consists of N-terminal cytosolic and C-terminal transmembrane domains. The N-terminal region of the cytosolic domain is homologous to small GTPase (G) proteins and is considered to regulate Fe(2+) uptake. The spacer region connecting the G and TM domains reportedly functions as a GDP dissociation inhibitor (GDI)-like domain that stabilizes the GDP-binding state. However, the function of the G and GDI-like domains in iron uptake remains unclear. Here, we report the structural and functional analyses of the FeoB cytosolic domain from Thermotoga maritima. The structure-based mutational analysis indicated that the interaction between the G and GDI-like domains is important for both the GDI and Fe(2+) uptake activities. On the basis of these results, we propose a regulatory mechanism of Fe(2+) uptake. Structural basis of novel interactions between the small-GTPase and GDI-like domains in prokaryotic FeoB iron transporter.,Hattori M, Jin Y, Nishimasu H, Tanaka Y, Mochizuki M, Uchiumi T, Ishitani R, Ito K, Nureki O Structure. 2009 Oct 14;17(10):1345-55.
