BRITE hierarchy
Sysname
2-amino-5-chlorophenol:oxygen 1,6-oxidoreductase (ring-opening)
Reaction(IUBMB)
2-amino-5-chlorophenol + O2 = 2-amino-5-chloromuconate 6-semialdehyde [RN:R10521]
Reaction(KEGG)
Substrate
2-amino-5-chlorophenol [CPD:C20669];
O2 [CPD:C00007]
Product
2-amino-5-chloromuconate 6-semialdehyde [CPD:C20670]
Comment
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.
