1.1.3.38 analysis development of a screening assay for the substrate specificity of para-phenol oxidases based on the detection of hydrogen peroxide using the ferric-xylenol orange complex method 763480 1.1.3.38 synthesis bienzymatic route from capsaicin to vanillin for biocatalytic production of natural vanillin with carboxyesterase and vanillyl-alcohol oxidase 655761 1.1.3.38 synthesis fusion of eugenol oxidase and 5-hydroxymethylfurfural oxidase to be used for dioxygen-driven, one-pot, two-step cascade reactions to convert vanillyl alcohol into divanillin and eugenol into lignin oligomers. At pH 5.5, the fusdion protein converts 92% of vanillyl alcohol into vanillin (53%) and a higher amount of oligomers (39 %), of which the most dominant product is divanillin 762907 1.1.3.38 synthesis synthesis of natural vanillin from capsaicin using a two-enzyme system of carboxylesterase from liver and vanillyl-alcohol oxidase 654161
