Cover Story: TrpNet is a comprehensive database and analytics platform to help researchers to understand tryptophan metabolism within the context of host and gut microbiome co-metabolism. It currently contains 108 tryptophan metabolites and 130 reactions across 5270 genome-scale metabolic models (GEMs), including 1246 and 88 bacterial species identified from the human and mouse gut microbiome, respectively. Users can browse, search, and highlight the tryptophan metabolic pathway, as well as predict tryptophan metabolites from a given taxonomy profile using Bayesian logistic regression models. TrpNet was able to better predict alterations in indole derivatives compared to other established methods based on two gut microbiome metabolomics studies. View this paper.
