Insights into the lifestyle of uncultured bacterial natural product factories associated with marine sponges.

ABSTRACT: The as-yet uncultured filamentous bacteria "Candidatus Entotheonella factor" and "Candidatus Entotheonella gemina" live associated with the marine sponge Theonella swinhoei Y, the source of numerous unusual bioactive natural products. Belonging to the proposed candidate phylum "Tectomicrobia," Candidatus Entotheonella members are only distantly related to any cultivated organism. The Ca E. factor has been identified as the source of almost all polyketide and modified peptides families reported from the sponge host, and both Ca Entotheonella phylotypes contain numerous additional genes for as-yet unknown metabolites. Here, we provide insights into the biology of these remarkable bacteria using genomic, (meta)proteomic, and chemical methods. The data suggest a metabolic model of Ca Entotheon
