WebL-Tryptophan decarboxylase ( EC 4.1.1.105) is an enzyme distinguished by the substrate L -tryptophan. [2] [3] This enzyme catalyzes the reaction of L -tryptophan to tryptamine and carbon dioxide. [2] [4] The enzymatic reaction namely takes place in the species Psilocybe cubensi s, where a decarboxylase, kinase, and methyltransferase work ... WebFeb 8, 2024 · SA suppression of CAT2 results in increased H 2 O 2 levels and subsequent sulfenylation of tryptophan synthetase β subunit 1, thus depleting the auxin biosynthetic precursor tryptophan. In addition, we find that CAT2 promotes JA biosynthesis by facilitating direct interaction of the JA biosynthetic enzymes ACX2 and ACX3, and thus SA repression …
