Activities in Family	Pyranose:oxygen 2-oxidoreductase / glucose 2-oxidase (EC 1.1.3.10); Alcohol oxidase (EC 1.1.3.13); Ecdysone oxidase (EC 1.1.3.16); Glucose 1-oxidase (EC 1.1.3.4); Aryl alcohol oxidase (EC 1.1.3.7); Oligosaccharide dehydrogenase (FAD) (EC 1.1.5.-); Glucose 1-dehydrogenase (FAD, quinone) (EC 1.1.5.9); Cellobiose dehydrogenase (EC 1.1.99.18); Pyranose dehydrogenase (EC 1.1.99.29);
Note	AA3 enzymes belong to the glucose-methanol-choline (GMC) oxidoreductases family. AA3 enzymes are flavoproteins containing a flavin-adenine dinucleotide (FAD)-binding domain. Family AA3 can be divided into 4 subfamilies: AA3_1 (mostly cellobiose dehydrogenases), AA3_2 (including both aryl alcohol oxidase and glucose 1-oxidase), AA3_3 (alcohol oxidase) and AA3_4 (pyranose 2-oxidase).
