A Parts List for Fungal Cellulosomes Revealed by Comparative Genomics

ABSTRACT: Characterization of proteins critical to fungal cellulosome assembly for Anaeromyces robustus, Neocallimastix californiae and Piromyces finnis (cellulosomes are multi-protein complexes that tether plant biomass degrading enzymes together). These findings suggest that the fungal cellulosome is an independently evolved fungal complex that co-opted useful activities from bacterial neighbors within the herbivore rumen microbiome.

Cellulosomes are large, multiprotein complexes that tether plant biomass-degrading enzymes together for improved hydrolysis<sup>1</sup>. These complexes were first described in anaerobic bacteria, where species-specific dockerin domains mediate the assembly of enzymes onto cohesin motifs interspersed within protein scaffolds<sup>1</sup>. The versatile protein assembly mechanism conferred by the bacterial cohesin-dockerin interaction is now a standard design principle for synthetic biology<sup>2,  ...[more]
