(A) Functional classification of the predicted proteins of the Lake Chalco sediment metagenomes, using SEED Subsystems. Samples are ordered from shallowest to deepest samples. Log2 normalization of abundance is shown. (B) Enzymes associated with different, presumably active metabolic pathways. Heatmap distribution of the enzymes (or subunits of the enzymes) of: (I) hydrogenotrophic methanogenesis (FmdA-MtrH), (II) shared key enzymes for all variants of methanogenesis (McrA-McrG), (III) acetoclastic methanogenesis (Ack-CdhB), (IV) methylotrophic methanogenesis (MtaA-MttB), (V) aerobic methane oxidation (PmoA), (VI) sulphur metabolism (SoxY-AprA), (VII) nitrogen fixation (NifH), (VIII) nitrification (AmoA) and (IX) denitrification NarG-NosZ), in the different sampled units. The numbers on the sidebar represent the abundance. Edited in CorelDRAW 2020 version 22.0.
