Abstract
A major indole-3-acetic acid conjugate from Phaseolus vulgaris seed has been isolated and partially characterized. It is a 3 kilodalton peptide with apparently 2 indole-3-acetyl moieties in amide linkage per peptide. The indole-3-acetic acid component was identified by gas chromatography-mass spectrometry and the peptide characterized by polyacrylamide gel electrophoresis, by amino acid analysis using dabsyl derivatives and by its Fourier transform-infrared spectrum. This is the first higher molecular weight amide-linked indole-3-acetic acid conjugate to be characterized from higher plants.
