IUBMB Comments
2-aminophenol:oxygen 1,6-oxidoreductase (decyclizing)
The enzyme, a member of the nonheme-iron(II)-dependent dioxygenase family, is an extradiol-type dioxygenase that utilizes a non-heme ferrous iron to cleave the aromatic ring at the meta position (relative to the hydroxyl substituent). The enzyme also has some activity with 2-amino-5-methylphenol and 2-amino-4-methylphenol [1]. The enzyme from the bacterium Comamonas testosteroni CNB-1 also has the activity of EC 1.13.11.76, 2-amino-5-chlorophenol 1,6-dioxygenase [2].
