TLDR
With both types of inhibitors the inhibition is reversible by higher substrate concentrations, but the Lineweaver-Burk plot is curvilinear suggesting the complex nature of competitive inhibition.About:

The mechanism of indole-3-acetic acid oxidation by horseradish peroxidases.
R. Nakajima,I. Yamazaki +1 more
TL;DR: The results suggested that the ferric enzyme is reduced by the IAA free radical but not by IAA itself, and it was concluded that the catalytic cycle of ferrous and oxyperoxidases is not involved in the I AA oxidase reaction.

Regulation of enzymic oxidation of indole-3-acetic acid by phenols: Structure-activity relationships
TL;DR: The number of hydroxyl groups and their position relative to each other and the nature and position of other substituents on the aromatic ring were found to affect the activity of mono- and diphenols.
Journal ArticleDOI
Effects of cinnamic acid derivatives on indole acetic acid oxidation by peroxidase
TL;DR: It is concluded that the inhibition is not only due to the radical scavenging properties of the inhibitors; direct interactions between the inhibitors and peroxidase also play a role in the unusual behaviour of the inhibition.
Journal ArticleDOI
Effects of phenolic substances on metabolism of exogenous indole-3-acetic acid in maize stems
TL;DR: In this article, four-day-old stem segments of Zea mays L. cv. Seneca 60 were treated sequentially with phenolic substances and indole-3-acetic [2-14C] acid.

Reaction Mechanisms of Indole‐3‐acetate Degradation by Peroxidases
Jacques Ricard,Dominique Job +1 more
TL;DR: Electronic mechanisms of reactions correlate the appearance and the disappearance of the various enzyme forms with known intermediates of indole-3-acetate degradation, and are associated with the formation of 3-methyleneoxindole as the major end-product of indoles3- acetate degradation.

The reaction between indole 3-acetic acid and horseradish peroxidase
Hiroko Yamazaki,Isao Yamazaki +1 more
TL;DR: On the basis of stoichiometric relation of reactions between IAA and peroxidase peroxide compounds a tentative scheme of P-670 formation during the oxidation of IAA was presented and IAA peroxide radical instead of superoxide anion radical was suggested to be an intermediate in the oxidation.
Journal ArticleDOI
The destruction of indoleacetic acid. II. Spectrophotometric study of the enzymatic reaction
TL;DR: Changes in the absorption spectrum during the oxidation of IAA by the Omphalia enzyme or horse-radish peroxidase indicate the formation and disappearance of an intermediate, which appears to consist of at least two, and possibly more, substances as soon as it is formed.
