[Biological activity of gamma-irradiated serum albumin].

: Gamma-irradiated serum albumin activated L-tyrosine oxidation to 3,4-dioxyphenyl alanine (DOPA) and forms adducts with DOPA oxidation products. These adducts are more resistant to proteolysis and have bactericidal and mutagenic capacity. A possible role of such adducts in a radiation damage to the organism is discussed.
