Pyranose dehydrogenase is a fungal flavin-dependent sugar oxidoreductase which is structurally and catalytically related to fungal pyranose oxidase and cellobiose dehydrogenase, and probably fulfils similar biological functions in lignocellulose breakdown. It is a monomeric secretory glycoprotein and is limited to a rather small group of litter-decomposing basidiomycetes. Compared to pyranose oxidase it displays a broader substrate specificity and a variable regioselectivity, and is unable to utilize oxygen as electron acceptor, using substituted benzoquinones and (organo)metallic ions instead. Depending on the structure of the sugar in pyranose form (mono-/di-/oligo-saccharide or glycoside) and the enzyme source, selective monooxidations at C-1, C-2, C-3 or dioxidations at C-2,3 or C-3,4 of the molecule to the corresponding aldonolactones (C-1), or (di)dehydrosugars (aldos(di)uloses) can be performed
