Functional annotation of five human microbiome proteome samples. Stacked bar chart showing the most abundant GO terms in each sample quantified by spectral counts. GO terms comprising the top 80 % of spectral counts (on average across all samples) are shown, with the others GO terms grouped into the “Other” category. Represented are the five healthy human fecal samples subjected to metaproteomics and the three technical replicates of each sample
