Vibrio cholerae FeoA, FeoB, and FeoC Interact To Form a Complex.
UNLABELLED Feo is the major ferrous iron transport system in prokaryotes. Despite having been discovered over 25 years ago and found to be widely distributed among bacteria, Feo is poorly understood, as its structure and mechanism of iron transport have not been determined. The feo operon in Vibrio cholerae is made up of three genes, encoding the FeoA, FeoB, and FeoC proteins, which are all req...
متن کاملThe FeoC protein leads to high cellular levels of the Fe(II) transporter FeoB by preventing FtsH protease regulation of FeoB in Salmonella enterica.
In the gammaproteobacteria, the FeoA, FeoB, and FeoC proteins constitute the Feo system, which mediates ferrous iron [Fe(II)] import. Of these Feo proteins, FeoB is an inner membrane Fe(II) transporter that is aided by the small protein FeoA. However, the role of another small protein, FeoC, has remained unknown. Here we report that the FeoC protein is necessary for FeoB protein-mediated Fe(II)...
متن کاملLon-mediated proteolysis of the FeoC protein prevents Salmonella enterica from accumulating the Fe(II) transporter FeoB under high-oxygen conditions.
The Salmonella Feo system consists of the FeoA, FeoB, and FeoC proteins and mediates ferrous iron [Fe(II)] import. FeoB is an inner membrane protein that, along with contributions from two small hydrophilic proteins, FeoA and FeoC, transports Fe(II). We previously reported that FeoC binds to and protects the FeoB transporter from FtsH-mediated proteolysis. In the present study, we report proteo...
متن کاملSolution structure of Escherichia coli FeoA and its potential role in bacterial ferrous iron transport.
Iron is an indispensable nutrient for most organisms. Ferric iron (Fe(3+)) predominates under aerobic conditions, while during oxygen limitation ferrous (Fe(2+)) iron is usually present. The Feo system is a bacterial ferrous iron transport system first discovered in Escherichia coli K-12. It consists of three genes, feoA, feoB, and feoC (yhgG). FeoB is thought to be the main transmembrane trans...
متن کاملSynaptic vesicle membrane proteins interact to form a multimeric complex
Potential interactions between membrane components of rat brain synaptic vesicles were analyzed by detergent solubilization followed by size fractionation or immunoprecipitation. The behavior of six synaptic vesicle membrane proteins as well as a plasma membrane protein was monitored by Western blotting. Solubilization of synaptic vesicle membranes in CHAPS resulted in the recovery of a large p...
