Effect of electron-beam irradiation on peroxidase
Present research work was conducted to evaluate the effects of iron chloride on peroxidase
enzyme activity in the fish, Labeo rohita.
Next, we examined which peroxidase
dominantly contributes to the onset of allergic airway inflammation using mice deficient in each of the three peroxidases
(Mpo, Epx, and Lpo) .
Within the confines of the RBC, autoxidation is minimized by the metHb reductase system; however free metHb can undergo a further peroxidase
reaction with [O.sub.2.sup.*-] to generate ferrylHb ([Fe.sup.4+]) and the ROS hydrogen peroxide ([H.sub.2][O.sub.2]) that in turn attacks Hb to produce protein radicals, irreversibly damaging the Hb molecule leading to heme degradation and release of free iron .
Sequence Comparison between Tg-Hb Subunits and Representative Peroxidases
. The amino acid sequence of the three Tg-Hb subunits was aligned with that of HRP and the MPO heavy chain (Figure 6).
were calculated by using the following formula:
have more functions than a Swiss army knife.
Bacteriazation caused significant rise in peroxidase
and soluble protein content under chromium (III and VI) stress and unstressed conditions.
O homogenato foi centrifugado a 10.000 x g a 4[degrees]C, por 10 min (Zeraik et al., 2008) e realizada a analise das proteinas soluveis totais (Bradford, 1976) e das seguintes enzimas:, catalase (Berrs & Sizer, 1952), ascarbato peroxidase
(Nakano & Asada, 1981), polifenoloxidase (Kar & Mishra, 1976) e peroxidase
(Fatibelho Filho & Vieira, 2002).
Activity of ascorbate peroxidase
was determined by the method described in Ref.
are widely distributed in plants, microorganisms, and animals where they play important roles.
