Tryptophan synthase plant
WebTryptophan (Trp), an amino acid with an indole ring (see Fig. 6-3), has long been regarded as the precursor of IAA in higher plants.Experiments utilizing radioactive tryptophan fed to intact or isolated plant tissues have been done for decades. The radiolabel incorporated into IAA is usually much less than expected, and there is always the possibility of microbial … WebIn contrast, plants also use the pathway to provide precursors for the synthesis of plant hormone auxin and plant secondary metabolites including glucosinolates and alkaloids. Like its counterpart in microbes, the plant enzyme, anthranilate synthase, catalyzing the first step of the pathway is feed-back regulated by the end product tryptophan [ Bernasconi94 ].
