Tryptophan decarboxylase 1

UniProtKB accession:  Q6ZJK7

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Involved in serotonin biosynthesis (PubMed:17763868, PubMed:19439571, PubMed:32595985). Catalyzes the decarboxylation of L-tryptophan to produce tryptamine, which is converted to serotonin by tryptamine 5-hydroxylase (PubMed:17763868, PubMed:32595985). May play a major role in serotonin biosynthesis during senescence (PubMed:19439571). Accumulation of serotonin attenuates leaf senescence (PubMed:19439571). Catalyzes the decarboxylation of 5-hydroxy-L-tryptophan to produce serotonin (PubMed:32595985).
