Crafting a better enzyme cocktail to turn plants into fuel faster
Date:11/3/2013

probe that binds to glycoside hydrolases and gives off information indicating just how active each of those enzymes is moment by moment.

"Identifying exactly which enzymes are doing most of the work you need done is crucial for making this an economical process," said Wright. "We're trying to keep tabs on the precise activity of every enzyme as each goes through a very complex process, as conditions like temperature and pH vary, to measure their activity through each stage."

"We can test the whole mixture, and we can also tease out each individual contribution. People have not been able to do that all at once before," added Wright, whose study was funded by PNNL.

Many of the measurements for the study, such as the measures of protein activity using mass spectrometry, were done at EMSL, the DOE's Environmental Molecular Sciences Laboratory on the PNNL campus. Wright's team included Lindsey Anderson, David Culley, Beth Hofstad, Lacie Chauvign-Hines, Erika Zink, Samuel Purvine, Richard Smith, Stephen Callister, and Jon Magnuson, all of PNNL.
