*The gene encoding this putative enzyme is on a contig with a nucleotide BLAST identity that matches the overall taxonomic identity for the MAG. Amino acid identities (AAID) to sequences in the hydrocarbon degradation databases are indicated by color (blue > 40% AAID, red > 30% AAID, and gray > 20% AAID).
