Iron(II)-mimosine catalyzed cleavage of DNA



Iron(II)-mimosine catalyzed cleavage of DNA



Zeitschrift für Naturforschung. C, Journal of Biosciences 55(9-10): 849-851



Supercoiled plasmid DNA was treated in vitro with H2O2, DTT and either Fe (II), Fe (II)-EDTA or Fe (II)-mimosine. The rate of DNA break formation was followed by the conversion of the supercoiled form into relaxed-circular and linear forms. In the concentration interval of 0-4 muM Fe (II), Fe (II)-EDTA slowed-down the formation of DNA breaks, while Fe (II)-mimosine enhanced the rate of break formation up to several times.
