Protein
4,5-DOPA dioxygenase extradiol
Function
Opens the cyclic ring of dihydroxy-phenylalanine (DOPA) between carbons 4 and 5, thus producing an unstable seco-DOPA that rearranges nonenzymatically to betalamic acid. Produces mainly (S)-betalamic acid. Required for the coloration of flowers.
Similarity
Belongs to the DODA-type extradiol aromatic ring-opening dioxygenase family.
