30 Jul 2020 --- A unified catalog of over 200,000 non-redundant reference genomes from the human gut microbiome has been created by an international research team. The Unified Human Gastrointestinal Genome (UHGG) collection compiles 171 million protein sequences from more than 4,600 bacterial species in the human gut, revealing its tremendous diversity. Combined with the team’s Unified Human Gastrointestinal Protein (UHGP) catalog, the collections will facilitate the exploration of the links between bacterial genes and proteins, and consequently, their effects on human health.
