Fig. 2From: New evidence for a hydroxylation pathway for anaerobic alkane degradation supported by analyses of functional genes and signature metabolites in oil reservoirsBootstrapped neighbour-joining phylogeny of ahyA and selected Mo-dependent hydroxylase gene sequences (outgroup not shown here). The sequences retrieved in this study are shown in red. Bootstrap support (1,000 replicates) > 50% is indicated at the nodes. The scale bar represents 20% amino acid sequence divergenceBack to article page
