Functional Metagenomics Characterization of an Anaerobic Saltwater Bioreactor

Figure 6

Comparison of key enzymes from different fermentative guilds. The relative proportion of key enzymes from the three shotgun datasets generated in this study are shown: formyltetrahydrofolate synthetase (FTHFS), acetate kinase (ackA) BuK, butyrate kinase (BuK), butyryl-CoA:acetate-CoA transferase (butyr-A-CoA), [FeFe]-hydrogenase ([FeFe]-H), [NiFe]-hydrogenase ([NiFe]-H), methyl-coenzyme M reductase (mcrA), and phosphofructokinase (pfk).
