Abstract:
Polypeptides were identified among translated coding sequences from a metagenomic cow rumen database, that were shown to provide xylose isomerase activity in yeast cells. The xylose isomerase activity can complete a xylose utilization pathway so that yeast can use xylose in fermentation, such as xylose in biomass hydrolysate.
