TrpNet is a comprehensive resource for researchers to visually explore, search, or predict tryptophan metabolism within the context of human and mouse gut microbiome. Its key features include
The gut microbiome is a critical regulator of its host homeostasis through the production of various bioactive metabolites which can be best exemplified by tryptophan derived metabolites. Tryptophan is an essential amino acid that undergoes complex host-microbiome co-metabolism leading to the production of an array of important metabolites including ligands of the aryl hydrocarbon receptor (AhR) such as Indoleacetic acid (IAA), indolepropionate (IPA) and Kynurenine (KYN) which are involved in host biological processes covering neuro-transmission, inflammation, and the immune response.
However, the existing pathway databases are mainly focused on the host tryptophan pathway and are not able to provide the information on tryptophan degradation across gut microbiome. Besides, not all tryptophan transformation are captured by these databases. Therefore, a comprehensive resource that covers the know tryptophan transform reactions and address the microbial contributors for tryptophan metabolites is necessary.
