Figure 6. Metagenomic insights into the genus Geobacter obtained by MEGAN analyses.
(A) Sub-genus level distribution of genes affiliated with the genus Geobacter based on BLAST homology. ‘Geobacter’ in the figures represents genes that were assigned to Geobacter at the genus level, but not to any genome-sequenced strain. (B) A partial MEGAN tree showing taxonomic distribution of genes encoding the acetate-catabolizing enzymes acetyl-CoA synthetase (EC 6.2.1.1), phosphate acetyltransferase (2.3.1.8), and acetate kinase (2.7.2.1), assigned to the class Deltaproteobacteria. LCA parameters: Min score, 50; top percent, 1.0; Min support, 2.
