Versatile Biocatalyst System for Synthesizing Chemicals, Pharmaceuticals and Food Ingredients
Robust and Modular Self-Assembling Protein Scaffold
An innovative protein-based scaffold optimizes the spatial connections among multiple enzymes in biocatalytic reactions. This technology uses a new type of self-assembling protein to form the scaffold and a better tagging system for attaching enzymes on the scaffold. This combination significantly improves biosynthetic efficiency with a robust and modular self-assembling protein scaffold (using the bacterial microcompartment shell protein EutM from Salmonella enterica) and methods to localize cargo proteins to the scaffold using SpyTag-Spycatcher. The protein scaffold includes EutM subunits and a multi-enzyme cascade of enzymes attached to the EutM subunits. The scaffold may be self-assembled, in vivo or in vitro, by incubating EutM subunits so they self-assemble into a protein scaffold. Scaffolding of enzymes can reduce diffusion of reaction intermediates and increase reaction efficiency. Synthetic scaffolds have been shown to significantly increase the function of different designed pathways.

Biocatalysis Spatial Organization Alternative
Industrial biocatalysis (using enzymes instead of chemical catalysts to transform organic compounds) is one option for producing valuable commodity chemicals, pharmaceuticals, and fuels that are difficult or impossible to synthesize chemically. Optimizing spatial organization of these enzymes (e.g., bringing enzymes in close proximity in cascade reactions) can significantly increase biocatalysis efficiency. However, biocatalysis is challenged in co-localization of enzymes in a cascade to optimize reaction conditions. Current strategies of spatial organization include 1) linking enzymes through fusion proteins, 2) immobilizing enzymes on solid surface with chemical linkers, 3) clustering enzymes on protein- or nucleic acid-based scaffolds, and 4) encapsulating enzymes in lipid or protein-based vesicles. This technology provides an alternative to these strategies by providing a self-assembling scaffold and attachment system that allows for co-localizing enzymes in multi-enzyme biocatalytic cascades.
