title: [Free iron in bacteria].
abstract: Free iron content has been estimated in autotrophic and heterotrophic bacteria. It constituted 40-50 micrograms/g dry weight as compared to 15 micrograms/g dry weight in animal cells. A method for estimation of free iron has been proposed. It is based on formation of paramagnetic dinitrosyl iron complexes by free iron and protein thiol groups or low molecular weight thiol ligands. The reasons for high iron content in bacteria have been discussed.
