EC 1.13.11.76     
Accepted name: 2-amino-5-chlorophenol 1,6-dioxygenase
Reaction: 2-amino-5-chlorophenol + O2 = 2-amino-5-chloromuconate 6-semialdehyde
Other name(s): cnbC (gene name); 2-amino-5-chlorophenol:oxygen 1,6-oxidoreductase (decyclizing)
Systematic name: 2-amino-5-chlorophenol:oxygen 1,6-oxidoreductase (ring-opening)
Comments: 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 from the bacterium Comamonas testosteroni CNB-1 also has the activity of EC 1.13.11.74, 2-aminophenol 1,6-dioxygenase.
