Enzyme Information
| 1.13.11.76 |
2-amino-5-chlorophenol 1,6-dioxygenase.
based on mapping to UniProt Q6J1Z6
2-amino-5-chlorophenol + O(2) = 2-amino-5-chloromuconate 6-semialdehyde.
-!- 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 1.3.1.74.
