A novel pathway for 2-aminophenol metabolism by Pseudomonas sp. AP-3 is proposed. The proposed pathway is similar to that known for meta-cleavage of catechol except that one of the hydroxyl groups on the metabolites is replaced by an amino group. During the degradation of 2-aminophenol, 2-amino-2,4-pentadienoic acid is the last metabolite containing an amino group. We, therefore, propose a modified meta-cleavage pathway for the 2-aminophenol metabolism.
