Extradiol dioxygenase that opens up the cyclic ring of DOPA between carbons 4 and 5 thus producing an unstable seco-DOPA that rearranges non-enzymatically to betalamic acid. Can also catalyze the formation of muscaflavin (a pigment found in the hygrocybe mushrooms family and of some amanita species only) by a 2,3-extradiol cleavage of DOPA. DODA Protein, Amanita muscaria, Recombinant (His & Myc) is expressed in E. coli expression system with N-10xHis and C-Myc tag. The predicted molecular weight is 33.6 kDa and the accession number is P87064.
