DESCRIPTION

Also known as GH315_ARATH, GH3.15. Indole-3-acetic acid-amido (IAA) synthetase that catalyzes the conjugation of amino acids to auxin specifically using the auxin precursor indole-3-butyric acid (IBA) and glutamine and, possibly, cysteine as substrates (PubMed:29462792, PubMed:30315112). Displays high catalytic activity with the auxinic phenoxyalkanoic acid herbicides 4-(2, 4-dichlorophenoxy)butyric acid (2, 4-DB) and to some extent 2, 4-dichlorophenoxylacetic acid (2, 4-D) as substrates, thus confering resistance to herbicides (PubMed:30315112).
