Interpretive Summary:

Technical Abstract: Glucuronic acid is a common chemical moiety that decorates the xylan polymer of hemicellulose. This chemical substituent impairs both anzymatic and acidic hydrolysis of xylosidic bonds. The alpha-glucuronidase enzyme hydrolyzes the 1,2-linked glucuronic acid from the terminal, non-reducing xylose of xylo-oligosaccharides. There are relatively few fÑ-glucuronidase genes in the public databases. We have developed an assay with commercially-available reagents that can be used to search DNA libraries for fÑ-glucuronidase genes in a high throughput, solid phase activity screen.
