Figure 4From: Molecular characterization of Clonorchis sinensis secretory myoglobin: Delineating its role in anti-oxidative survivalPeroxidase activity of r Cs Mb and mutants evaluated by spectrophotometry. Reactions were performed with H2O2 (20 μM) and oxygenated rCs Mb solutions at 20 °C and pH 7.0. The A0/A ratio is the initial absorbance and final absorbance at 407 nm. All mutants containing Y34A did not show H2O2 reactivity, and only Y68A exhibited lower reactivity than that of wild-type Cs Mb.Back to article page
