1-INDOLEACETIC ACID

Canadian Journal of Chemistry, 1952
1-Indoleacetic acid, 3-methyl-1-indoleacetic acid, and several of their derivatives were formed from phenylhydrazineacetic ester, and their structures were determined in three different ways. Several of the new compounds exhibited plant growth regulating activity.

Indoleacetic Acid Oxidase Activity of Apoperoxidase

Science, 1967
The conventional activity of electrophoretically purified horseradish peroxidase toward guaiacol, pyrogallol, 2,6-dimethoxyphenol, and benzidine is abolished by removal of the heme prosthetic group with a mixture of cold acetone and hydrogen chloride.

Activation of Citrate Synthetase by Indoleacetic Acid

Nature, 1969
SARKISSIAN1–3 has reported that partially purified citrate oxaloacetatelyase (CoA–acetylating), EC 4.1.3.7 (citrate synthetase), from bean hypocotyl, pig heart, corn scutella or castor bean endosperm was activated by indoleacetic acid (IAA). Although it was thought that the effect on the enzyme was allosteric, involving sulphydryl groups, Zenk and ...

Fluorescence and photoinactivation of indoleacetic acid

Archives of Biochemistry and Biophysics, 1951
Abstract These results indicate quite clearly that the induction of the photoinactivation of indoleacetic acid (IAA) is by no means a peculiarity of riboflavin but is a property common to many fluorescent substances. It is not essential that the compounds be colored. Colorless materials are also able to bring about IAA photoinactivation provided that

Direct and dye-sensitized aqueous photo-oxidation of 3-indoleacetic acid, methyl-3-indoleacetate and 1-methyl-3-indoleacetic acid 1-methyl-3-indoleacetic acid II: Quantum yields and mechamism

Journal of Photochemistry and Photobiology A: Chemistry, 1990
Abstract Mechanisms accounting for the types and yields of the products obtained in direct and dye-sensitized photo-oxidation of the compounds 3-indoleacetic acid (1a), methyl-3-indoleacetate (1b) and 1-methyl-3-indoleacetic acid (1c) in aqueous buffer (pH 5 or pH 8) containing 10% methanol are discussed.
