RT Journal Article ID 2c4032f65911215b A1 Konovalov, Yu. D. T1 Metal-binding Proteins of Mature Fish Eggs JF Hydrobiological Journal JO HYD YR 2001 FD 2001-08-01 VO 37 IS 4 OP 13 AB It was shown that amounts ofthioneins enriched in free-reacting SH-groups and binding the Hg2+, Cd2+ Cu2+ and Zn2+ ions are increased in the cytosol and mitochondria of fish eggs under the action of these cations. Cations of heavy metals, being the components of a protein complex, differently influence the properties of metal-binding proteins and it appeared in an inhomogeneity of their ultraviolet absorption spectra.
