متن کاملDiversity and ecology of and biomineralization by magnetotactic bacteria.
Magnetotactic bacteria (MTB) biomineralize intracellular, membrane-bounded crystals of magnetite (Fe3 O4 ) and/or greigite (Fe3 S4 ) called magnetosomes. MTB play important roles in the geochemical cycling of iron, sulfur, nitrogen and carbon. Significantly, they also represent an intriguing model system not just for the study of microbial biomineralization but also for magnetoreception, prokar...
متن کاملEngineering intracellular biomineralization and biosensing by a magnetic protein.
Remote measurement and manipulation of biological systems can be achieved using magnetic techniques, but a missing link is the availability of highly magnetic handles on cellular or molecular function. Here we address this need by using high-throughput genetic screening in yeast to select variants of the iron storage ferritin (Ft) that display enhanced iron accumulation under physiological cond...

Mcissbauer spectroscopy is a nuclear i-rav resonance technique that has been extensively tv!i 'iill' s,,'stems. applied to the study of the electronic properties of iron in biological '. The power of the technique lies in its sensitivity to the effects of the physical environment (nature ]18 lw and disposition of ligands, magnetic structure, etc.) on 57Fe nuclei. Moreover, it is sensitive ' onl...
