title: [Factors influencing formation of dinitrosyl complexes of non-heme iron in vitro preparations of mouse liver and yeasts].
abstract: Total content of Fenh and its amounts incorporated into paramagnetic dinitrozyl complexes of Fenh (complexes 2.03) which are formed in vitro in homogenates of mouse liver and yeast preparations treated with nitrogen oxide was determined by means of chemical and ESR methods. Formation of the complexes 2.03 in the liver homogenate is limited by the content of easily dyalized weakly bound Fenh, in yeasts--by the content of pair RS-groups. It is suggested that in the liver preparation Fenh incorporated into the complexes 2.03 is determined by the interaction of reduction cytoplasm agents with ferritin. A change in the content of Fenh may affect the appearance and disappearance of the complexes 2.03 in animal tissues in vivo.
