show Brenda entryEC number
1.10.3.4
Accepted name
o-aminophenol oxidase
Reaction
4 2-aminophenol + 3 O2 = 2 2-aminophenoxazin-3-one + 6 H2O
Other name(s)
isophenoxazine synthase,
o-aminophenol:O2 oxidoreductase,
2-aminophenol:O2 oxidoreductase
Systematic name
2-aminophenol:oxygen oxidoreductase
CAS registry number
9013-85-8
Comment
A flavoprotein which catalyses a 6-electron oxidation. The enzyme from the plant Tecoma stans requires Mn2+ and FAD [1] whereas the fungus Pycnoporus coccineus requires Mn2+ and riboflavin 5′-phosphate [2], the bacteria Streptomyces antibioticus requires Cu2+ [4] and the plant Bauhenia monandra does not require any co-factors [3].
