Overview of the viral functions of cnGVC. a Construction of a nonredundant gene catalogue from the cnGVC viral genomes. b Rarefaction curves of the number of nonredundant viral genes and no-singletons as a function of the number of all viral genomes. c Venn plot showing the sharing relationship between gut viral genes and prokaryotic genes. d Functional composition of the virus-specific genes, prokaryotes-specific genes, and shared genes. Functions are categorized at the KEGG pathway level B. e Composition of viral auxiliary metabolic genes (AMGs) for each viral family. AMGs are grouped at the KEGG pathway level B and sulfur-related metabolism. The bar plot (upper panel) shows the overall proportions of AMGs versus the number of annotated genes for all viruses, and the heatmap (bottom panel) shows the proportions of AMGs versus the number of annotated genes for each family. Distribution of virus-encoded carbohydrate-active enzymes (CAZymes) (f), virulence factor genes (VFGs) (g), and antibiotic resistance genes (h) for each family. For CAZymes and VFGs, only the top 30 enzymes are shown
