The mechanism of metabolic degradation of indol-3-ylacetic acid (39) is a matter of debate. A possible route demonstrated in vitro includes oxidative decarboxylation to skatolyl hydroperoxide (40), catalyzed by horseradish peroxidase isoenzyme C (HRP-C), followed by rearrangement to 3-(hydroxymethyl)oxindole (41), as shown in equation 12 . [Pg.616]

Generation of CIII from GS occurs when the enzyme acts as an oxidase in the presence of superoxide ion. This reaction has been observed in horseradish peroxidase isoenzymes C and A2 [28, 53, 63], lignin peroxidase [46], myeloperoxidase [69], and bovine liver catalase [64], The rate constant for the reaction of GS with superoxide increases with a decrease of pH suggesting that the reacting species is HO2 instead of C - [64], The physiological relevance of the hydroxyperoxyl radical has been recently reassessed [70],... [Pg.296]
