Promotion of Indoleacetic Acid Oxidase Isoenzymes in Tobacco Callus Cultures by Indoleacetic Acid [PDF]
Plant Physiology, 1971 Indoleacetic acid oxidase in tobacco callus cultures (Nicotiana tabacum L., cv. White Gold) was composed of at least two groups of isoenzymes, which were distinctly different in electrophoretic mobilities and in responses to growth substances. Indoleacetic acid had dual effects; at low concentrations it promoted the development of two fast-migrating ...

Formation of indoleacetic acid by intestinal anaerobes [PDF]
Journal of Bacteriology, 1975 Indoleacetic acid was produced from tryptophan by only three of 23 intestinal anaerobes studied. Evidence is presented to show that the formation of indoleacetic acid proceeds through the intermediate, indolepyruvic acid, via transamination with alpha-ketoglutarate rather than by tryptamine pathway.

Metabolism of Indoleacetic Acid in Rust Diseases. II. Metabolites of Carboxyl-labeled Indoleacetic Acid in Tissues [PDF]
Plant Physiology, 1964 In a previous paper (6), we reported different rates of decarboxylation of indoleacetic acid (IAAC14OOH) by healthy and rust-affected wheat leaves in the dark. As a result of infection the rate of decarboxylation first increased, but several days later, as the rust began to sporulate, declined to become much lower than that of healthy leaves.

The destruction of indoleacetic acid. III. Relationships between peroxidase action and indoleacetic acid oxidation [PDF]
Archives of Biochemistry and Biophysics, 1960 Abstract The indoleacetic acid (IAA)-oxidizing enzyme preparation from Omphalia flavida exhibits peroxidase activity on pyrogallol with an optimum at pH 3.5–3.7, like that for the IAA-oxidizing activity. It shows no polyphenolase activity. Peroxidase and IAA-oxidizing activities run parallel both during thermal inactivation and in course of ...
