Fig. 4.

Comparison of the KEGG methane pathways of the 5 archaeal GBs (Eu01–05). In the upper part of the figure the reference KEGG methane metabolism pathway is represented, in the lower part archaeal GBs’ genes present and absent in the pathway are highlighted. Genes identified in the archaeal GBs were labeled with a small colored dot. Genes absent in the GBs and present in the reference genomes are marked with a “X” (Eu01–Eu02—Methanoculleus marisnigri; Eu03—Candidatus Methanoplasma termitum; Eu04—Methanosarcina acetivorans; Eu05—Methanothermobacter thermoautotrophicus). Genes identified in the GBs and absent in the reference are labeled with a circled dot
