Article Title: An enzyme-level benchmark based on environmental bacterial laccases for predicting contaminant fate in water
doi: 10.64898/2026.01.27.701970
Figure Lengend Snippet: (A) Approximate maximum-likelihood phylogenetic tree of the multicopper oxidase MCO1 from Nitrosomonas sp. and two new laccases experimentally validated in this study from a methane-oxidizing bacterium (mMCO, NCBI ID: HEY7867587.1) and a soil ammonia-oxidizing archaeon (aMCO, HYV56308.1) displayed relative to other uncharacterized homologs in global metagenomic datasets colored by metagenomically-assigned phylum of origin. (B) Biogeographic distribution of MCO1 homologs from samples where location information was recorded in environmental sample metadata. Two samples were from notably contaminated sites: Red triangle = soil site contaminated with 1000 mg Cr (VI) kg - . Red circle = crude-oil contaminated marine sediment site.
Article Snippet: The National Center for Biotechnology Information (NCBI) non-redundant protein sequences database (nr) was queried using BLASTP with the above-listed stringent homology parameters, resulting in 960 unique protein sequences.
