Fig. 6From: Modification of substrate specificity of l-arginine oxidase for detection of l-citrullineCalibration curve for l-citrulline using the dehydrogenase assay. The dehydrogenase assay was measured after incubation in 200 mM phosphate buffer (pH 6.0) with 2.7 μM enzyme (ArgOX or ArgOX/E486Q) at 37 °C (●: ArgOX, ◯:ArgOX/E486Q). Values are presented as mean ± standard deviationBack to article page
