Fig. 5From: Uncovering the genomic potential of the Amazon River microbiome to degrade rainforest organic matterMain protein families potentially involved in the last steps of the lignin-derived compound metabolism. The O-demethylation and C1 metabolism of compounds is shown in terms of protein families and taxonomy (left), as well as the ring cleavage step that directs the substrates to pyruvate, which enters into the TCA cycle to be converted into ATP and CO2 (right)Back to article page
