The present study addresses the microbiome of the first whale fall (YOKO 16) that has been described in the deep sea in the southern Atlantic Ocean (Sao Paulo Plateau; 4204 m depth), in terms of its metabolic uniqueness. Sets of ten thousand protein sequences from YOKO 16 and 29 public domain metagenomes (SRA and GenBank databases) that represent various marine, terrestrial and gut-associated microbial communities were analyzed. The determination of protein functionality, based on the KAAS server, indicated that the YOKO 16 microbiome has industrially-relevant proteins, such as proteases and lipases, that have low similarity (similar to 50%) with previously-described enzymes. The amino acid usage in the YOKO 16 protein sequences (based on blastp and Clustal analysis) revealed a pattern of preference similar to that of extremophiles, with an increased usage of polar, charged and acidic amino acids and a decreased usage of nonpolar residues. We concluded that the targeted microbiome is of potential biotechnological use, which justifies the allocation of resources for the discovery of enzymes in deep-sea whale fall communities.
