A newly discovered way of optimizing plant enzymes through bioengineering has increased knowledge of how plant material can be converted into biofuels, biochemicals and other high-value products.
The University of Adelaide-led study presents innovative ideas for how the walls of plant cells can be assembled, structured and remodeled by controlling specific enzymes' catalytic function. Theand was conducted with an international, multidisciplinary team of researchers from the Institute of Chemistry of the Slovak Academy of Sciences and the Huaiyin Normal University in China.
Studying the catalytic function of specific enzymes—a process termed"xyloglucan xyloglucosyl transferases"—allowed researchers to better understand how they link diverse polysaccharides to form structural components of plant cell walls. "This work contributes to the essential knowledge of how xyloglucan xyloglucosyl transferases can be understood and their fundamental properties controlled—for example, to improve their catalytic rates and stability," said project leader Professor Maria Hrmova.to be used in the production of biofuels, plant cell walls need to be deconstructed and the resultant materials chemically processed.
"Although the definition of the catalytic function of xyloglucan xyloglucosyl transferases has significantly progressed during the past 15 years, there are limitations, and still a lack of information, in how this knowledge can be organically implemented in the functionality of plant cell walls," she said.
