Rule bt0388

Pattern 4159        All patterns
4-Aminophenol derivative -> 1,4-Dihydroxybenzenoid
4-Nitroaniline derivative -> 4-Nitrophenol derivative
2-Aminophenol derivative -> vic-Dihydroxybenzenoid
3-Aminophenol derivative -> 1,3-Dihydroxybenzenoid
o-Benzoquinone derivative -> vic-Dihydroxybenzenoid

Aerobic Likelihood:              Neutral

EAWAG-BBD Reaction(s):
4-Aminocatechol -----> 1,2,4-Benzenetriol (reacID# r1608)
Aminohydroquinone -----> 1,2,4-Benzenetriol (reacID# r1497)
5-Nitroanthranilate -----> 5-Nitrosalicylate (reacID# r1722)

This rule handles the aminophenol pathway. It includes initial oxidation followed by rapid hydrolysis of an o-, m- or p-aminophenol derivative to form an o-, m- or p-benzoquinone, respectively (bt0105). The p-benzoquinone intermediate is quickly reduced to a 1,4-dihydroxybenzenoid (bt0107), while the o-benzoquinone intermediate is similarly reduced to a vic-dihydroxybenzenoid. This rule handles the known benzoquinone intermediates in this pathway, based on Zhao et al., 2000 and Kutty et al., 2000. This rule also handles the 5-nitroanthranilate amidohydrolase reaction, which might include a transient benzoquinone intermediate, based on Qu and Spain (2010).

bt0387: 4-Aminobenzenesulfonate derivative --> 4-Hydroxybenzenesulfonate derivative
