General description

3-Indoleacrylic acid (IAA) is a chemical used for the induction of gene transcription. This expression system requires that the gene of interest is cloned in plasmids containing the trpE promoter.

Application

Suitable for induction of gene transcription in systems controlled by the trpE promoter.

Biochem/physiol Actions

3-Indoleacrylic acid helps to block the mycelial growth of Neurospora crassa. As a result, the cells accumulate indoleglycerol phosphate, which influences the rate of tryptophan synthetase.

Shoot branching and growth are controlled by phytohormones such as auxin and other components in Arabidopsis. We identified a mutant (igi1) showing decreased height and bunchy branching patterns. The phenotypes reverted to the wild type in response to RNA interference

In a previous paper, we demonstrated that the medium-chain fatty acyl-CoA dehydrogenase-catalyzed (MCAD-catalyzed) reductive half-reaction of indolepropionyl-CoA proceeds via formation of a chromophoric intermediary species "X" (absorption maximum = 400 nm) and proposed that the decay of this species might

An approach to the optimization of product yield in an inducible inclusion body-producing system is presented. Following induction by indoleacrylic acid (IAA) of a trpLE-HIVgp41 fusion protein, we found a large increase in culture turbidity and single-cell dry weight. After
