Iron-Associated Outer Membrane Proteins of Magnetic Bacteria.
Abstract
Iron-associated cell outer membrane proteins (FeOMPS) of magnetic bacteria are the focus of this research. In addition to determining effects of iron and oxygen supply on FeOMPs, several potential roles of these external cell proteins will be investigated to determine how they may participate in 1) iron binding and reduction to mobilize it inward 2) detoxification of activated forms of O2 and 3) the synthesis and/or release of a soluble c-type CO-binding cytochrome. The relationship of Fe OMPs to cell magnetite precipitation will be explored with the use of mutant strains. An effort will be made to document the principal cellular location and role in cell physiology and magnetosome formation of a CO-binding soluble c-type cytochrome which is selectively released from cells of a magnetic spirillum by freezing and thawing.
