Fig. 5From: Two superoxide dismutases from TnOtchr are involved in detoxification of reactive oxygen species induced by chromateEffect of several metal ions on SOD activity of purified ChrC (a) or ChrF (b) enzymes. Lane1, enzymatic reaction in absence of any tested compound; lane 2, enzyme incubated with chromate, lane 3, enzyme incubated with Cr(III); lane 4, enzyme incubated with Fe(II); lane 5, enzyme incubated with Mn(II); lane 6, enzyme incubated with Ni(II); lane 7, enzyme incubated with Zn(II); lane 8, enzyme incubated with Cd(II); lane 9, enzyme incubated with Cu(II)Back to article page
