Figure 2. Assignment of microbial taxa to BMI-associated enzymatic functions. Heatmap showing the assignment of microbial taxa to 10 enzymatic functions previously identified as positively associated with BMI and enriched in obese individuals. Taxa include those identified in the taxonomic meta-analysis as BMI-associated, as well as additional contributors revealed by back-tracing analysis. Green cells indicate assigned taxa, defined as taxa whose mean relative abundance was equal to or greater than the 90th percentile of the corresponding function-specific back-tracing profile; black cells indicate taxa below this threshold. BCAA: Branched-chain amino acid; BMI: body mass index.
