Fig. 4: Completeness of select metabolic pathways of interest in 2017 abundant high-completion MAGs determined using MetaSanity, and Fe oxidation and reduction genes annotated using FeGenie (Supplementary Data).

Genes considered in calculating pathway completeness are shown in parentheses, with the exception of carbon cycling pathways, where genes considered are shown in Supplementary Data. Completeness of each enzymatic pathway is expressed as a percentage (0–100%). Bar graph at right depicts counts of extracellular proteases and carbohydrate-catabolism enzymes in each MAG (complete dataset available in Supplementary Data). Refer to Fig. 2 for color assignments of taxa.
