Researchers from the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) have gained new insights into how glycosylation—the natural attachment of sugars to proteins—affects a key cellulase enzyme. This work could be used to improve enzyme performance to better break down biomass and convert waste plant matter to renewable fuels and products. Namely, the more effective the enzyme, the more efficient and economical the process will be.
