Fig. 4From: Uncovering the genomic potential of the Amazon River microbiome to degrade rainforest organic matterTransporters of lignin-derived compounds and funneling pathways of dimers and monomers in the Amazon River. The number of genes as well as taxonomy per protein family is indicated. The TTT system is depicted with (“?”) as its involvement is hypothetical. Funneling pathways to monomers and dimers are shown in terms of gene family and taxonomyBack to article page
