Extended Data Fig. 7: Phylogenetic tree of sulfide oxidizing enzymes.

Phylogenetic relationships between the beta subunit of Flavocytochrome c sulfide dehydrogenase (FCC) and Sulfide:quinone oxidoreductase (SQR). The scale bar represents the expected number of changes per amino acids position. UFBoot and SH-aLRT values are based on 1000 replicates. Best substitution model: LG + R4. Sulfurimonas species are in bold.
