Insights into putative alginate lyases from epipelagic and mesopelagic communities of the global ocean.

ABSTRACT: Alginate lyases and oligoalginate lyases catalyze the cleavage of the glycosidic bonds of alginate, an acidic polysaccharide synthesized by brown algae and other organisms. These enzymes are highly diverse, currently classified into 15 families of the Carbohydrate-Active Enzyme (CAZy) database. We explored the structural and taxonomic diversity, the biogeographic distribution of the genes and transcripts, and the potential environmental drivers of putative alginate-degrading enzymes from picoplanktonic communities of the upper layers of the global ocean. The identified sequences were first analyzed using sequence similarity networks to assess their relationship with CAZy members. Sequences related to the PL5, PL6, PL7, PL17, and PL38 families had higher gene and transcript abundances, with
