Fig. 5: Predicted metabolic models for anaerobic oxidation of gaseous alkanes based on archaeal MAGs harboring mcrA genes.

a Archaeal oxidation of methane; b archaeal oxidation of ethane; and c archaeal oxidation of butane. Red font indicates that not all MAGs retrieved encode the enzyme (numbers of MAGs encoding the enzyme are indicated in parentheses). Dashed lines indicate steps catalyzed by unconfirmed enzymes. SC alkanes, short-chain alkanes. Percentages above each panel indicate the completeness of the corresponding MAGs estimated by CheckM. Details on the annotation of the enzymes are presented in Supplementary Data 10.
