4.1.1.74 malfunction an ipdC-knockout mutant grown in the presence of tryptophan has decreased indole-3-acetic acid level (46% of wild type strain) -, 714125 4.1.1.74 metabolism IpdC id involved in indole-3-acetic acid biosynthesis -, 714125 4.1.1.74 physiological function in a mutant lacking IpdC activity, the level of substrate indole-3-pyruvate is 2.3fold higher and the level of indole-3-lactic acid is 2.1fold higher. Phenylalanine metabolism is impacted by the loss of IpdC in the mutant strain as well as glucosinolate biosynthesis pathway -, 749276
