[https://www.uniprot.org/uniprot/TRPDC_RUMGV TRPDC_RUMGV] Catalyzes the decarboxylation of tryptophan to tryptamine. Tryptamine is a neurotransmitter that induces the release of serotonin, which is suggested to modulate gastrointestinal motility. Therefore, the tryptophan decarboxylase from the gut bacteria Ruminococcus gnavus (strain ATCC 29149 / VPI C7-9) may influence host brain and behavior. Has weak activity with tyrosine and phenylalanine.<ref>PMID:25263219</ref>

Several recent studies describe the influence of the gut microbiota on host brain and behavior. However, the mechanisms responsible for microbiota-nervous system interactions are largely unknown. Using a combination of genetics, biochemistry, and crystallography, we identify and characterize two phylogenetically distinct enzymes found in the human microbiome that decarboxylate tryptophan to form the beta-arylamine neurotransmitter tryptamine. Although this enzymatic activity is exceedingly rare among bacteria more broadly, analysis of the Human Microbiome Project data demonstrate that at least 10% of the human population harbors at least one bacterium encoding a tryptophan decarboxylase in their gut community. Our results uncover a previously unrecognized enzymatic activity that can give rise to host-modulatory compounds and suggests a potential direct mechanism by which gut microbiota can influence host physiology, including behavior.
