Figure 2From: Isolation and characterization of mutated alcohol oxidases from the yeast Hansenula polymorpha with decreased affinity toward substrates and their use as selective elements of an amperometric biosensorChronoamperometric assay of ethanol by HRP/Os-Ap59//AOX/CP9 biosensors based on the native (nAOX) and mutated AOX (mAOX) forms of alcohol oxidase and the derived calibration curves. Arrays indicate step-wise addition of ethanol in different concentrations.Back to article page
